Title: Blending normal maps together in 3ds Max
Post by: theOrzel on 2014-07-14, 17:44:14
Hello,
I've been playing around with normal maps and I cannot figure out how should I blend 2 normal maps together within 3ds Max.

My set-up:
Normal Map "MEDAL" - general object surface bumps
Normal Map "CRACKS" - details like cracks, scratches
Composite node - it's suppose to blend 2 input textures
CoronoaNormalTex - used as suggested to get normals working properly
CoronaMlt

set-up: https://dl.dropboxusercontent.com/u/896453/Material_setup.PNG

I would like to blend these 2 textures together in 3ds Max. Normally I would use Overlay blend mode inside PS and get final texture, but this I would like to have more control over scratches intensity and/or texture tiling.

I made 4 tests:

Composite with Overlay blend mode

Composite with Normal blend mode (50% top layer opacity)
(https://dl.dropboxusercontent.com/u/896453/blendingNormals_2.jpg)

Composite with Average blend mode
(https://dl.dropboxusercontent.com/u/896453/blendingNormals_3.jpg)

Textures from Photoshop - Overlay blend mode
(https://dl.dropboxusercontent.com/u/896453/blendingNormals_4.jpg)


Overlay Blend mode in composite node is totally wrong. Test 2 and 3 gives the same result but I don't know if it is correct.
Can somebody elaborate a little bit about this? I'm confused and don't know how should I blend normal maps


regards,
Michal

Hi. Did you find any solution without photoshop?

Most likely overly mode don't work in max, because OP has loaded normal maps with gamma 2.2. If loaded with gamma 1.0 blending works as expected, no need photoshop here.

Thanks man! That helps me.
I always tried with corona gamma fix option enabled.
