BeginScene failed in StartRenderSurface

[DanDixon]

I'm getting the following error in the debug file when I turn on glow:

Code:

05-21-2008 22:43:37 | TEXTURE MANAGER : BeginScene failed in StartRenderSurface, be sure to draw on rendersurface outside the usual TV.Clear/TV.RenderToScreen block

However... Glow works just fine and I'm quite certain that I'm doing what it says to do (only drawing on a rendersurface outside the TV.Clear/TV.RenderToScreen block).

My project also has as 3D mode (requiring red/blue glasses) which works great, yet this error is generated when I enable that (as it also works with a render surface).

My glow code is as follows:

Code:

            rsGlow.StartRender(False)
            World.DrawBackground()
            rsGlow.StartRender(True)
            Scene.RenderAll(True)
            rsGlow.EndRender()
            GraphicFX.UpdateGlow()

Then I draw the world:

Code:

            TV.Clear()
            World.DrawBackground()
            TV.Clear(True)
            Scene.RenderAll(True)
            Phys.DrawLabels()
            GraphicFX.DrawGlow()

Some additional code that draw the UI, etc. And finally:

Code:

            TV.RenderToScreen()

So again... Everything works, but the debug file would suggest otherwise. And this error is generated every frame, so the debug file gets really big.

Any thoughts on why this happens?

Thanks...

Glow works just fine and I'm quite certain that I'm not doing what it says I am (drawing on a rendersurface outside the usual TV.Clear/TV.RenderToScreen block).

I assume that's just a slip of the tongue. Do you mean you're sure you *are* doing what it tells you to do?

Yes... That's what I meant.    I corrected the original message.

Any idea why I get these errors in the log file?

Well, you have these lines..

rsGlow.StartRender(False)
World.DrawBackground()
rsGlow.StartRender(True)

Now I'm pretty sure I know why you're doing that, but I wonder if TV does. To TV, it might look as though you're trying to render a second rendersurface when you haven't finished rendering the first one. Can you not safely call rsGlow.EndRender() before calling StartRender() a second time, or does that defeat the purpose?

[jviper]

Is there a call to the RSGlow.EndRender anywhere inside the World.DrawBackground() or in it's stack? If not, then you will need to add a RSGlow.EndRender after World.DrawBackground(). Also, the World_Drawbackground cannot call RSGlow.StartRender, or you'll run into the same problem.

[DanDixon]

So that was an easy fix:

Added another "rsGlow.EndRender()" after the background is drawn and before the 2nd StartRender.

Code:

          rsGlow.StartRender(False)
            World.DrawBackground()
            rsGlow.EndRender()
            rsGlow.StartRender(True)
            Scene.RenderAll(True)
            rsGlow.EndRender()
            GraphicFX.UpdateGlow()

Application works the same way, but the errors are no longer showing up in the debug output.

Cheers to jviper and sybixsus.
