Sweeeeeet! That worked out perfectly! Its 2LI each now. Brilliant. Thank You. I have learned a lot from this thread, appreciate it

Using the single vertex method, I have managed to reduce physics from 2.5 to 0.5 on mid floor. But the sides are going way out the roof. 17K to 53K of LI! 🥺 Mid Floor Physics with Triangle to cover Z axis in BB Mid Floor Physics with Single Vertex Method (with a big plane on ceiling surface) Side Floors Physics with Single Vertex Method (with a big plane on ceiling surface) Top View Bottom View Uploading only one side (the side @Aquila Kytori have redone the physics) Physics made in my original file, following the vertex method steps The same mesh & LODs but physics changed to the physics model made by Aquila Cross-checking My Physics (left) & Aquila's Physics (right) All the dots seems to be in same position. Single vertex is the number 0 on both. I did even redo the physics and tried. Still don't work on mine! Correct, its physics was low. The problem was in Download which had a difference until I reduced few tries from Low LOD on both side before I posted 2nd time. I tried to keep the shape without loosing too much details as it is a building. In your example, it seems to me that it works pretty much like box physics method where number of tries don't really matter! I did want to have a plane on all sides, so no one can get in and out of the roof 😄. In my mind the less tries on physics, it cost less on physics cost. That is why I lowered it 2 tries. I got few others that needs to correct Download without loosing its shapes (see below). 3LI for a small door and 13LI for front wall on ground floor (the 1st floor front wall also have a hole but it is 4LI. both these have 3 materials). Physics is now below 0.5 on all the parts, except the 2 floors. Is there any way I could lower Download Cost other than reducing tries from the LODs? and does physics effect download?

Thank you @Beq Janus & @Aquila Kytori for that awesome & quick reply. As you both mentioned about a possible auto-generated thin triangle on uploading process, I looked into the one I have uploaded already (below is a pic of auto-generated physics of the Floors in in-world). Then tried manually converting physics quads to tries in Blender, making both have same size tries. But still, somehow Land Impact vary. It is because, I got some more mesh for side woods :3 (see the links to files below) So, the walk-able surface is just about the center of Mesh. I have removed that 2 thin tries on sides (next to stair way) as there will be a wall that goes over it which has its own physics. Made it 1 triangle instead to cover height (its visible on above pic). I could eliminate this triangle as well with above method right? by adding 2 vertices (for top and bottom) Links to Blender Files High LOD & Physics | Med LOD | Low LOD | Lowest LOD Somehow roofs match now after I reduced few tries on low LOD. Floors: when i export & upload from the newly saved file I have attached, it gives (L) 4 - 2 (R) LI. When exported from original file it gives (L) 6 - 3 (R) LI

I made the following 3 stores. For each of these stores, I got a separate roof, floors and walls on each side. I first made the centre store, then made the right side and mirrored it to left. Applied the transformations, baked all textures & made all LODs. Those 2 sides have same number of materials, same number of vertices & tries (as per Blender). But somehow, I get two different Land Impacts on left & right roofs & 1st floors. Everything else matches. Below are the LI when those are set to Prim (Physics Shape Type). Both have hole for stairway. Dimensions are same (both physics & mesh) Left (LI) Right (LI) Remark Roof 3 4 Convex Hull LI (left - right): 3 - 4 Both have same physics, download & server weight. But more display weight is different (L)1826 - (R)1831 - Both side carries 3 textures. Only difference i found was 4 extra vertices on left (this side happens to give low LI than the other) All LODs have same vertices & tries (as on upload window) Both roofs have physics of 2 tries 1st Floor 3 2 Convex Hull LI (left - right): 2 - 2 Both have same download, server & display weight Somehow Mesh is high on left. Thus high physics - Both dimensions are same & I have double checked if it goes beyond boundary. all good. Only difference I found here was 1 extra vertices on right (this side happens to give low LI than the other) All LODs have same vertices & tries (as on upload window) This is after I managed to remove 2 physics tries from each. Before it gave 6 - 3 (left - right) LI (in Prim mode) Both floors have physics of 8 tries Floor Upload Window So I'm quite puzzled about this & curious to know whats the cause and how could it be fixed or at least a way to lower the LI.
