shader bug (alpha 3)

[Ocram]

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?

[Ondra]

yes, post the scene please. ;)

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

[Ondra]

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.

[Ondra]

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

[Ludvik Koutny]

I already logged this into our bug tracker. Thank you for discovering this problem :)

...Thank you for discovering this problem :)

you welcome :)

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