Hello,
This is a first proof of concept about generating a vector displacement from any arbitrary model.
There is still a lot of unknown, and areas I need to test :
- Trying different smooth algorithm to remove overlapping geometry when flattening the model in Houdini.
(Maybe using the one used to flatten uv texture). This is the area that takes a bit a computing time.
- I wish to find a way to write negative value in .exr generated in Houdini, to avoid to do a refit from a normalized texture in Terragen (seems to work, but Min and Max value to re-apply the vector displacement map have to be entered by hand)
- Terragen smooth interpolation in the image map shader seems to wash a lot of details (especially around the ears in this case). Disable it make the model too ugly (faceted). Furthers test need to be done, maybe an higher resolution from Houdini model can helps a lot.
The result is not that bad so far
