Another quick entry with my tips&tricks for Modo.
This time I’m going to write about setting up Mudbox’s vector displacements in Modo.
- Check your displacement in Mudbox and clean your layer stack as much as you can. This will make faster the extraction process.
- The extraction process is very simple. Just select your low and high resolution meshes.
- Set the vector space to Absolute if you asset is a static element, like props or environments.
- Set the vector space to Relative if your asset will be deformed. Like characters.
- Always use 32 bit images.
- As I said export the maps using EXR 32 bits.
- Before moving to Modo or any other 3D package, check your maps in Nuke.
- Once in Modo, select your asset and go to the geometry options.
- Check Linear UVs and set the render subdivision level.
- Assign a new shader to your asset.
- Add a new texture layer with your vector displacement map.
- Set it up ass Displacement Effect.
- Set the low and high value to 0 and 100.
- You will see a displacement preview in viewport.
- Set the gamma to 1.0 Remember that 32bit images shouldn’t be gamma corrected using Linear Workflow.
- In the shader options set the Displacement Distance to 1m this should give you the same result than Mudbox.
- In the render options you can control the displacement rate, which is your displacement quality more or less.
- 1.0 is fine, play with that. Lower values will give you sharper results but will need more time to render.
- Finally render a quick test to see if everything looks as expected.
