[r197] Using object transp. makes Shaders use screen coords

Problem Description

As title says - if an object has transparency applied or another Shader in the stack before a Shader that works with coordinates, the coordinates in use become screen-space and not object-space.

I tried to discuss this here: but there was no reaction so here's a bug report using the built-in fx.

Attach a Capx

Description of Capx

We have the same sprite with the same effect applied, but the one on the right has a different opacity.

Steps to Reproduce Bug

Change the opacity of anything that has a coordinate-dependant Shader.

Observed Result

The sprite with transparency applied uses screen-space coordinates.

Expected Result

The sprite with transparency should still use local coordinates.

I added some more details to the thread you linked to.

Because this depends on the way the rendering pipeline works, it is probably pretty difficult to fix. However I'll leave the issue here open to indicate a known issue.
