quick reply, my elbow really hurts at end of day. I think your best bet is to try to limit dissolves of each of your 1607 meshes.
1- select mesh. Best to click in mesh list to get them all.
2- change to edit mode using TAB key toggle. Note the tris are just this mesh now.
3- Select all vertices (A key). You may have to do this twice depending on how things were left for this mesh.
4- Bring up delete menu (X key)
5- Pick limited dissolve
Because of flat nature of most stuff, you probably do not need anything, but you will see a Limited dissolve in the bottom left. I get better results when delimted by UV’s. You can increase angle, but square ness probably means 5 id good. Note tris now, should be lower. If for some reason it looks really bad for this mesh, undo (crtl-Z)
Hi. Your buildings to complex. Look at roof… some constructions build with polygons? I think you need planes with textures because your roofs constructions is not main focus objects. the same goes for road dividers and other high-poly objects. you need to distribute objects according to the degree of importance in the frame and, depending on the importance or constant presence in the field of view, optimize objects that are less important. if the player must look at an object close and not in motion, it must be higher polygonal with textures of higher resolution, otherwise the further and less important object in the scene, the fewer polygons it should be. in any case, before proceeding with the optimization, it is necessary to study the general techniques for optimizing the game scene. you cannot just take and dump a bunch of objects on the stage
I’ve now got a model that’s 500k triangles, 234k faces and 1.6m verts. I’ve loaded it on the sandbox and whilst I’ve lost a lot of quality, it actually moves around with a decent framerate. Thanks for your help everyone. Now to work with Babylon
I’ve just done the limited dissolve, I wasn’t sure what else you meant re the angles.
