I’m really having problems with the decimation modifier. I have large triangular meshes that I need to decimate (often >3M tris).
The problem is that some regions are ‘over-decimated’ while others don’t hardly decimate at all. I know this is because of the underlying geometry/topology, but I can’t find any solution. Even if I only decimate by 0.9, or 0.95 I get really poor results.
See pictures below.
This is really critical to my work so if there’s any advice or suggestions thank you very much.
Note that I’ve been using Meshlab lately to decimate with some success but results are not very good either and it is very tedious to export and reimport multiple objects just to decimate… I really need to keep it in Blender for scripting purposes.
After 0.9 decimation (very badly shaped tris). I’ve tried relaxing to improve but the tris are too distorted.
Again, any help much appreciated.
