00346: Sometimes bumpmap shading is inverted on some triangles

« 00345 | Issues | 00347 »

Summary: Sometimes bumpmap shading is inverted on some triangles

Created: 2011–05–06 09:52

Status: Released

Category: Bug

From: brad

Version: 2.1

Released_In: 2.2

Description:

It appears that some triangles compute the normal incorrectly when using a bump map especially when the bumpmap is applied using a non-linear mapping like spherical mapping.
