Title: light projection image mapping
Post by: szymon.bochenek on 2021-12-10, 12:37:04

Hi,

I`m searching how to archive effect from attachement.
How to project image on 3d model with light.

Do you have any solution for this kind of effect in Corona Renderer in 3dsMax?

Best regards!
Szymon

I found semi-solution (plane with CoronaBitmap on CoronaLightMaterial and directionality=1) but projected image is blured.
File in attachement.

Do you have any other ideas?:)

Best regards,
Szymon

3dsmax standard lights have a projection option.

Thanks balatschaka, I will try with standard lights too when I will not archive it witch Corona solutions.

I see that when light source is close to objects , then image is good enough in some cases.
File in attachement (the same parameters then before but light is as close as possible to objects).

Anyone can help with reducing noice in this case?

Best regards,
Szymon

PROBLEM SOLVED!
I put standard directional light with corona shadow and Bitmap projection. It works amazing, image is sharp and render very fast!

Thanks balatschaka for this advice with standard lights!!

Best regards,
Szymon
