Title: Rotating texture
Post by: jojorender on 2022-01-12, 20:33:25

Corona V.7
What is the best/ fastest way to rotate a texture inside a material?
The projection shader and corona seem to hate each other…
The C-bitmap shader has a ton of UV controls but no rotation? Why not?

Try Transform in a Layer Shader.

Thanks Mike,
this works in a c4d bitmap but not in a corona bitmap.

@ dev team
I assume someone already requested this. No need to request again?

No?

Preview yes, but try to render.

Blooming glare, well I never!
Should have tried to render it, indeed.
Sorry.
Shows how rarely I use a Corona Bitmap shader actually.

Hey Mike, are you able to send us this test scene as well? Thanks also to jojorender for bringing this to our attention.

I am facing the same problem with layer/transform, was it solved?

Hello,

no, this was not solved yet.

Thanks,
Jan

I tried it in Corona 10 and the problems exist here too.
In the meantime, is there a solution to rotate the texture in a Corona bitmap?
If you have hundreds of individual parts, you can't rotate the texture in each one using coordinates.

I have bumped the issue ;)

As a workaround, can you try this with the projector shader to see if this resolves the issue?

Or a transform in a layer shader.

I did try that but it was not working with a Corona bitmap, only a standard C4D bitmap. This is why I was hoping the projector shader might be a replacement for rotation with the Corona bitmap.

Yes, it seems to be working with the C4D bitmap only.
The projector shader should work as well but it still scares me a lot - it was a bit unreliable in the past.
