Hello,

I have a small grid (64*64 row/columns), uv coordinate (0,1), and a custom point attribute called “custom” (vector)
And I have no clue how I can create a little texture (64*64, .exr), to store this custom attribute.

- I have tried the ‘simple bake’ from the gamedevtools, but I always have .py error when I try to add my Custom Channels.
- I have tried to use the Vertex color baking (still with the gamedevtools “simple bake”), storing my custom vector in a @Cd (point), but negative component of my vectors return a 0 value in the baked image.

Maybe it's possible to import my grid in a COP, but I'm not really sure about the procedure (seems to work with heightfield, so maybe I should convert my grid as an HF and transfer my attribute).

Any hint to send me in the right direction would be really appreciated.

Thanks

Hello,

I think I'm starting to understand the texture baking in Houdini.

So the question is a little bit different, how can I save signed .exr ? (.exr is supposed to support negative value right ?)
