    Thanks, I looked at these shortcuts and some of them didn't make sense. I thought it was Ctrl+Alt+Shift+I

    Did some more work in Blender and this is what I have so far. Not exactly what I want and still need to add some texture.

    I am not sure if this is the right place to ask a stupid question but someone told me the multibutton hot key to hide your avatar. Any ideas what that command is, I wanted to take some more pictures of my terrain without the avatar.

    Thanks for everyone's help and feedback. The path to an understanding how to build a descent mountain based on an existing terrain has been surreptitious and nonlinear. I was a little surprised and had to learn how to use Blender (more), L3DT, Photoshop, etc to get something that was "good enough" and I am not done, lol. Doing some of this work is not for the faint of heart. You need time and a lot more than just Second Life to build something like a mountain. Even just getting the info from the existing terrain.raw file was difficult (got lead astray by a YouTube video that was not totally correct). I am working on getting Opensim setup (to view terrain.raw files) and still want to explore Meshroom (to build mesh models from photographs). Again, thanks for your help

    There was another YouTube video that I found that described using the Knife. It really was the first approach I used. I have done some of what you have said but I am a little slow at some of the details. Blender is a great free tool that has so many possibilities. I still have not used the join option and still have not figured out how you move am edge up to create a slope. This is not an extrude along z. I figured it out you grab the lines and just move them up along the Z axis. I notice that most of the faces I see in your model are tris, are they easier to work with when building a model?

    Thanks, I have wondered about building multi-mesh models and then linking them in world. Decimation was really one of the first things I was exposed to with Blender. I was also thinking about textures for the model and how a terrain has 4 textures based on elevation. Maybe multiple models could improve the texturing of the model.

    I have used the media player (web browser) to display images in Second Life. Everything works well except my monitors are set to 1920 x 1080 and when I select the face of the browser the image over zooms. If I change my monitor to 175% or use the camera controls I can view the entire but the Auto Zoom doesn't seem to work. OBTW, "Web on a Prim" is discussed in the YouTube video - Is there a way to fix this? Thanks

    I was pretty much ok with the cost L$15 but the land impact was 128 and download was 128 (Tris = 3517, Quads = 2041). I thought if I drew it in Blender I could reduce the impact and maybe even use it for a physics model. In Addition, I wanted to respect your initial response since you have been so extremely helpful. Also, I did no decimation on the terrain based model so I could reduce the mesh complexity

    Hello, sorry I a late to the post. I was looking for a viewer script but I wanted to access the images via a internet site. Can the script be modified for that?

    I was pretty much ok with the cost L415 but the land impact was 128 and download was 128 (Tris = 3517, Quads = 2041). I thought if I drew it in Blender I could reduce the impact and maybe even use it for a physics model. Also, my original desire was to make a mesh model with the least amount of pain. Since SL has been around a while I figure that it would be easy but it was not. In Addition regarding my switching back to drawing it in Blender, I wanted to respect your initial response since you have been so extremely helpful. Both you and ChinRey as well as others have helped me and I appreciate it. I did no decimation on the terrain based model so I could reduce the mesh complexity even more but I still need to texture the drawing. I will review your suggestion above and thanks you so much for taking the time an effort to help educate me, lol.

    Thought I would go back and try to draw this up in Blender following Aquila's suggestion. Using the info previously provided in the YouTube video I was able to draw an outline of the island mountain with very little problem. Then I added some addition ridges that were near the edge of the island. I was even able to extrude and scale the mountain and did some smoothing but I am a little stumped on adding the ridges and slopes on the lower part of the island. Maybe I can use a Bevel?
  12. IvyTechEngineer
    Yes, you can use Photoshop, I am using 2020 and no major issues but the video I found on it has some misinformation.
  13. IvyTechEngineer
    Thank you very much, that fixed it.

    Another riddle - I was able to create several dae models using two different terrain files. One with the original terrain and the other one with a terrain that only had the mountain island in it. Both could be uploaded to SL with any issue. Then I tried to reduce the mesh to only the mountain island and tried to upload it. I did not do anything but delete or dissolve vertices, lines or faces and when I export as a DAE and try to upload I get this error. https://www.ivytechengineering.com/SecondLife/files/mountain_only_terrain.dae produced by L3DT (cost L$17 for upload 5879 Tris and 2992 vertices but Major Land impact 200 https://www.ivytechengineering.com/SecondLife/files/mountain_only_terrain.blend Blenderr File https://www.ivytechengineering.com/SecondLife/files/mountain_only_terrain_Blender.dae DAE model works fine for upload (cost L$18 for upload 5879 Tris and 3001 vertices but Major Land impact 205 SL sets the scale to 0.251 which lead to a 63.9x63.9x11.257 https://www.ivytechengineering.com/SecondLife/files/more motorA.blend Used Blender to reduce the mesh and mirror the mountain around the Y axis https://www.ivytechengineering.com/SecondLife/files/mountain_onlyA.dae Fails to upload 5687 Tris and 2895 Vertices according to Blender This one scaled to to 10% but still doesn't upload. Suggestions?

    I was reading an old post in on Bundysoft (L3DT) and a guy wrote a script that might help convert the terrain.raw file. http://www.bundysoft.com/wiki/doku.php?id=scripts:import_opensim_raw_file http://www.bundysoft.com/phpBB2/viewtopic.php?f=4&t=2718 These are pretty old posts, maybe 2013.

    I am getting closer to a solution with this (building a floating mountain that looks like the mountain that I currently have). Others have proposed using L3DT to create a DAE file but I need to figure out the image format needed to convert the terrain.raw file. Others have suggested redrawing the mountain/island in Blender which seems simple enough but still is a pain. I could buy something that is close enough through SL Marketplace and just relocate the objects that are on the island. There is another the possibility to use Meshroom. This program can create a high rez model using photos and metadata in photos. This seem very interesting but I don't know how to modify the images to include the appropriate metadata to make it look like a "photo" so that Meshroom can use it. The final option is to build something in SL that is close enough, download it, modify it in Blender and add texture and then upload it.

    Next up I need to see if I can get the L3DT to work to create the mesh ...

    I think I have figured out the terrain puzzle. Say you want terrain that is 60 meters above the ocean with two other levels that are at 40 meters and 20 meters. Then one solution could be R = 240, 160, 80 with a G = 32. The G channel is set to 32 where 240*(32/128) = 60. This would lead to a gain of 0.25 or 240*0.25 = 60. Here are some files that might help you based on the flatgreen.raw file that is talked about in the YouTube video above ... https://www.ivytechengineering.com/SecondLife/files/60m_flatgreen.raw https://www.ivytechengineering.com/SecondLife/files/terrainheight.xlsx

    Somewhere buried in this thread is a question about faking out Meshroom by using images captured in SL and adding fake photo metadata. I have watched a few videos on fixing photos. I am not sure exactly what metadata is needed and whether the a screen captured image can be converted into a photo. Any suggestions?
  20. IvyTechEngineer
    Just tried Meshroom on a set of images I captured from a mountain I have in SL. It failed because "focal length could not be determined" for the pictures. Also there are missing meta data. Maybe this info could be added to a SL image?

    Holly cow Batman, that is totally awesome! I know I have too many vertices and some are not really very useful. This was my first attempt at trying to make a mesh model from a terrain. Trying to decipher the terrain.raw file has been a nightmare so I thought I might be able to do something in Blender. Initially, I wanted a model that was a close approximation of what I currently have. Along that line I think I could take some take pictures of the terrain with the reference plane adjusted in 5 or 10 meter changes in elevation. This would give me a series of pictures that could be used to build the mesh. I really appreciate your help and advice.
  22. IvyTechEngineer
    Thanks for the response. I have been messing around and decided to recreate it in Blender so I was able to clear items from above the island and take a picture looking down. Then I imported the image into Blender and used it as a reference to create a terrain I could extrude. This is what I have so far. https://www.ivytechengineering.com/SecondLife/files/island4.blend Watched this YouTube video to build what I have...

    This almost makes no sense because in my terrain.raw file the G channel is just 46 for all pixels or the scale factor is 0.36 times the R channel value for every pixel in the image. Seems somewhat silly and superfluous since we can easily scale objects in SL. I still am puzzled by the Photoshop file for the R channel. It looks like I have a variation of 0 to 128 or so. This would mean more variation than I am seeing in the BW png file. I have asked a photoshop friend if she could help. So to import a terrain.raw file it is Widthe = 256, Height = 256, Channels Count = 13 and the Interleave needs to be on and the Depth is 8 Bits with a Header Size of 0. OBTW, I cannot increase the Depth to 16. I also attempted to review the ASCII file of the BW png file and it doesn't show much variation.
