Title: Multi Layer Displacement
Post by: kahein on 2015-11-04, 12:13:16

Displacement only work in the base material.
- we cant mix displace with multiple material
- IR VFB doesn't update with just a base material (nothing in the layer mat) and in this base material with a CoronaMix plug in the displacement map. Play with the value, swtching map, changing map etc IR doesn't update correctly until i close it and re open

Confirmed. Some displacement limitations.

The second line is about having Corona Mix plugged into displacement slot of base material of Layered mtl. It does not update changes unless restarted/regular render. Mix tex works fine if not nested inside Layered base.

sorry to dredge this up, but I just came across this problem myself, has it been fixed for 1.4?

Hi, has this been fixed?

So I guess it is not possible to create a material with multiple displacements? I am creating a tyre and I basically need to have two displacement maps, one for the thread pattern and one for the channels and both need to have different values/depths. I've tried making it with CoronaLayeredMtl but I only get the displacement from the base material.

plug that displacement map into a CoronaDisplacementMod

hi guys

i think is the same problem ....
 
iam using corona layer material and sometimes i have issues different reactions in iR

Bump.


I'm trying to create a layered material that uses a coronadistance map to make a beachfront material (grass transitioning to soft sand, transitioning to wet sand underwater, all driven by an altitude range or the water as the distance object)

All 3 ground materials have displacement maps which i'd like to include.

What would be the best way to go about creating this?

Hi slowgojoe.

All displacement maps has to be placed in the base layer, so you need to build a layered displacement map (nested mixmaps) with the same masks that are used in layered materials.

This is quite cumbersome, but until Corona makes it possible to read the displacement maps from all layered materials, this is the way to go.

Hope it helps

Thank you, that works!
