Rendering artifacts with volumetrics + object texture with alpha transparency
Closed, ResolvedPublic

Broken: 2.69.10 cc7cfd6

Short description of error
When an object with textured alpha transparency is inside a volumetric object, its transparent areas show up in a weird way.

Also, some weird light streak appears inside the volume. The errors might to be related, because if I delete the objects inside the volume, the streak goes away.

Attached image for clarification.

Exact steps for others to reproduce the error
Open my attached scene, and activate viewport rendering.
Add a cube. Set up a volumetric scattering material. (Absorption type doesn't have this error.)
Add a plane. Set up a material with clearly visible transparent areas. Place inside cube.
Add a light source.
