Scatter Based on density texture from COP

[ferlodavid]

Hi all,

I'am trying to scatter points in texture space on a low poly mesh based on a modify texture inside copnetwork, i put op:/..../cop2net1/output on density texture reference and node says "failed to load density texture, unrecognized file type " but only works if i put a file or default.pic.

I'm lost, please help me what iam doing wrong?

 

Thanks so much

Here is the basic setup. Using an attributeToMap you can convert COP based colors into Cd for points on geometry. Then in the scatter node just Cd, not density, to drive the scatter.

Thanks so much for the answer but this method is not valid for me, i have a low poly mesh if i use attibutetomap(i use this for heightmap) in a mesh with not enough points i lose texture definition for scatter instead of texture space. My problem is load a texture generated in cop in texture density on scatter, i tried with op: tex or pic but i cant get it, if i load a file directly i can.

Can you post an example file with the problem?

I need to load density texture from cop network but gives error, only works with files.

Sorry i didnt explain well

I see what you mean, I would call it a bug and file it with SideFX.

But in the mean time you can just attribute by map to fetch from COPs and then scatter by Cd. I don't know what you expect to gain by using texture space? And you could just write out the file from COPs and load it in as a file if your work flow insists on using texture space. In the end you will just have points scattered on your geometry.
