Title: shader bug (alpha 3)
Post by: Ocram on 2012-10-10, 10:56:34

Hi Keymaster,
I'm getting a bug with the Corona material :(
Here a render of a simple scene (one cylinder + 1 corona light).

Let me know if you need the max's file.

Aren't you using a strong bump map?

Hi Rawalanche,
I don't think so, but to be sure I attached the file max...

I've looked at the file - there is bump - and pretty strong one. If you disable/lower it, it renders OK

Hi Keymaster,
thanks for the reply but I don't agree with you :)
if you see this image, bump works very nice with a procedural map but it shows (also with low value) the problem I wrote you with the bitmap.

The its something I'll have to investigate ;) can you post shading normal and dot product shading passes?

Filterig was off for the texture in bump slot. You need to use filtering to get reasonable results with bump mapping
