mViewportModifierMask = 0x00 ignored for PassClear with Direct3D 11
Setting passClear->mViewportModifierMask = 0xFF does not seem to have intended effect when Direct3D 11 is used. Instead of clearing only the viewport area of the render target, it clears the entire target. With OpenGL3Plus it works as intended.

Re: mViewportModifierMask = 0x00 ignored for PassClear with Direct3D 11
Hi!
I wanted to reply to your other post but unfortunately I didn't make it in time (your questions require long and complex answers).
This is something I wanted to warn you about: D3D11 does not allow clearing partial regions. Metal doesn't either. Only OpenGL allows it (at the cost of performance, since partial clears aren't fast). We corrected this mismatch in 2.2 (which is WIP) by having OpenGL behave the same way D3D11 & Metal do to avoid this kind of confusion.
Unfortunately, clearing using pass_clear only works on the whole render target.

Re: mViewportModifierMask = 0x00 ignored for PassClear with Direct3D 11
Hi,
No problem :)
Ok, thanks for the info.
I changed my system slightly to do a full clear on the final render target before the per-viewport workspaces (if there is at least one viewport which want to render directly to the final render target, i.e. it does not have any post effects). I did this by adding a "clear" workspace that only have one node with a clear pass. Not sure if it is OK to have a workspace that only clears..?
But anyway, I stumpled upon the problem described in this post viewtopic.php?f=25&t=94104 which has somewhat blocked me from really testing the clearing stuff further.
