Automate converting alpha vegetation to mesh

Most vegetation we buy where I work seem to rely heavily on alpha which slows Cycles down. Has anyone here converted such vegetation to geometry instead, and if so, how did you go about it? For example, the first step is to separate everything into loose parts (built-in command): [image] Then we can set the pivot for each mesh to center of mass (also built-in command): [image] But now I need something which identifies similar meshes and then converts them to instances so I only have a fe…

Convert alpha cards to full geometry - how do I round the edges?

Hello! I’m trying to cut out alpha cards from the texture to make foliage full geometry for Unreal Engine 5.6 that uses the material on opaque instead of masked. I managed to do this geometry nodes but I can’t make the edges more rounded which causes small visual bugs in Unreal Engine. I was also able to do this for small plants specifically because I need to do this and for tree leaves which are much more complex. Does anyone have an idea how I could do this? Thanks in advance!

Image 2 Mesh [GeoNodes]

Hi there! I just released a GeoNodes setup that turns any 2D image into a pixel-perfect traced and tessellated mesh. It’s available to buy here on Gumroad. Appreciate your support

I “remembered” them a bit .. and refound by the awesome forum search function (top right –icon ) .
