EN: When I made some Big details scene with overall 30m polys and my IPad starts lagging. Of course you can use just Decimate - but its kills your paint details!
I try to find the wat to fix that. And I finded it!
This method can be useful for different scenario. For example you can export your scene in Gbl/Obj file formats with textures to Blender without any problems. And if you try to Export 30m poly mesh without optimization/retopo from Nomad to Blender - you will get Big laggs.
There is no other way than using reproject high detail and vertex paint to a low detail mesh with UVs and textures and normal textures imho.
But isnāt that just a standard function?
Clone, decimate, create UVs then reproject from high res?
But Razum gets nice results, maybe he has some special tweaks?
