Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to display texture with alpha or mask on the spectator screen without adding a new SceneCapture ?

Hi everyone,

Here is my spectator screen :

alt text

The red square is my clear color from my render target.

I just want it to be transparent.

If I understood correctly, "SetSpectatorMode(TexturePlusEye)" it just adding a texture to display on the spectator screen behind or in front of the Eye texture. It could be awesome to get that Eye texture and add a material to it (maybe on the next version, with the "Viewport" spectator screen mode).

Anyway I just want to add a tranparent texture for adding the brand of my client. And because I make my demonstrations with a laptop I can't add a new SceneCapture for performance issues.

Has anyone succeed to do it ?

Bests :)

I'm also trying to do this. Rendertarget texture alpha channel doesn't seem to do anything here.

In fact, without digging into the engine, you can't. -_-
