Attempting to upload my first mesh to SL that I created in Blender. I'm fairly new to this whole 3d modeling/texturing thing so it's been a fun, interesting and yes, sometime frustrating learning process. My first mesh is a porch roof extension for my LL home. I've run into a couple issues though I can't find a solid answer to or maybe I'm just bad at searching.
1. Is it necessary or better to do PBR textures or is a combined texture bake fine for a LL home addition? Obviously 3 textures costs me more to upload than a single and in my current project, I'd be looking at like 24 textures with PBR vs 8.
2. Bigger question. My project, in total, is showing as having about 950 triangles or a little over 2k vertices. Which, from the sounds of it, isn't really that bad. I've read about meshes with like 40k triangles. Note: this object is broken down into separate mesh objects within the same file (mostly for texturing purposes) like rails, columns, header, fascia, roof and then packaged into a collada file. My question is: when I have the various sections of my porch rails joined together in blender, I get the degenerate triangle error when uploading to SL. When I simply separate them and then try to upload, I get no error. Obviously, I could just separate it and run with it but I'd rather ask the question to see if anyone might know why its happening to better understand it for the future. I'll add too, I've gone through all the vertices and edges, one by one, to find any issues but came up empty handed and I can't zoom in on the preview any closer than shown in my photo.
