Resolved bugs / CoronaCamera
« on: 2018-06-06, 20:57:48 »
I have found a bug while animating CoronaCamera and its target.

I think the issue might be related to the target's orientation.
The target perhaps should not orient itself toward the Camera; this usually ends up in a loop.

I leave you a short screen-capture (1 min, no audio).


Note:
As a temporary fix, I parent the target under a locator, and I'm animating the locator instead.

With warp map I mean a map that can distort a texture based on another texture.

This is a way to add detail to an ambient occlusion or a curvature map (check this other feature request).

As a reference you can look at the work that John Burnett has put on github.
I know that this plugin it is free and with the source code, but I would rather have it directly in Corona because:
  • it is a plugin, meaning I have to hope that someone will update it in time when a new version of 3dsmax will came out
  • it is a plugin, meaning I have to hope that the render farm supports it
  • it is a plugin, each person on the team needs to have the same version (?)

Another take on this subject is the Transition node in Mari, but I still have to check what this node does.



I think that it would be useful to have a shader for detailing procedural masks.
What do think about this request?
Anyone sharing the need for this feature?

Feature requests / Curvature Map
« on: 2015-12-08, 18:38:25 »
A curvature map can be used to generate procedural wear on the edges of objects.

As a reference for the workflow you can read this article by Neil Blevins and you can take a look at how the Quixel Suite 2.0 generates its masks for layering materials.

Currently you can bake the curvature into the mesh vertices or buy a plugin like GeoMaps.

Personally I don't like these solutions because:
  • you have to bake the curvature for each mesh you want to apply the shader on
  • baking the curvature needs a quite detailed mesh to work
  • baked curvature is geometry dependent, you have to re-bake when you change the mesh
  • GeoMaps is a plugin, meaning I have to hope that they will update in time when a new version of 3dsmax or Corona came out
  • GeoMaps is a plugin, meaning I have to hope that the render farm supports it
  • GeoMaps is a plugin, each person on the team needs to have the same version (?)




I think that it would be useful to have a dedicated curvature map in Corona.
What do you think about this request?
