Try with this code to do ALT-TAB and going back : crash!

Perhaps a bug ?

I've found the reason ... Sprite3D and Engine3D are not fully compatible

Syntax

RenderWorld()
Description

Renders the whole world on the screen. This function should be called once all 3D operations are finished and only one time per frame.

Once the RenderWorld() function has been performed, it's possible to use regular 2D functions like DisplaySprite() to display 2D sprites over the 3D world (note: Sprite3D is not supported though).

Code: Select all

   #D3DBLEND_ONE=2

I've answered on the bug thread to not "pollute" this one. If you want I can delete my post...
