Summary:
Solidify Modifier makes mesh texture missing in OpenGL render

Detailed description

My system : Ubuntu 10.10 64bit. AMD Turion X2 64bit. NVIDIA Gforce 9100m G.

I try to make an openGL render routine, to see my animation in realtime (playblasting). All mesh that using Solidify Modifier is missing their texture. All the texture works well when i disabled the solidify modifier.

Kindly please check the attachment below. Thank You

The attachment is missing. In our bug tracker is a bug (yes really), so make sure you press "save changes" while the tab "Attachment" is open.

A similar bug also affects meshes with a Mask Modifier applied. When doing an OpenGL animated render, textures are ignored, but when OpenGL still render is used, textures are drawn normally (i.e. like in the 3D viewport normally). Objects without this modifier are perfectly fine.

Checking around my harddrive for some old builds, this issue doesn't seem to exist back in 2.52 (specifically when the "bullet2" gsoc branch was branched from trunk), but it does appear in current versions (at least from r34842 till current trunk r35459).

The "body" mesh has a mask modifier, so lacks textures, while the shirt doesn't have a mask modifier and has textures. Removing the mask modifier solves the problems.

This doesn't happen
* if any other setting is used then 'Render to window'
* if armature is deleated (when armature is hidden the bug still happens)
* solidify enabled (as mentioned)

also reloading the texture ot toggling mipmap settings wont make the texture show.

fixed r35469.

the second window was using a datamask without UV layers so the solidify modifier was recalulated without them.
now all windows are used to calculate the datamask before use.
