Hi cryengeneers! I need render to texture, for feature in game - preview window on panel bar for characters (Icon with animated head)
Is there someone know how to achive this on c++ with newest cryengine 5.5 ?

Render to texture is not in the engine, this question has been raised many times in the community. The technology is probably not the most complicated, it is present by default in any other engine. But Crytek does not react at all. There is an opinion that maybe the game Hunt: Showdown uses Render to texture, usually the technologies that Crytek use in their games migrate to the national engine, but all this is in fantasy

thanks for reply noise
so pity
crytech plz add this most wanted feature to yours engine

This is amazing! I do not know Render to texture or some interpretation of this technology. But I just want to see similar technologies in the engine out of the box. What are some basic technologies that can expand gameplay

Render to Texture in Lumberyard https://docs.aws.amazon.com/en_us/lumbe ... xture.html Now this technology is exactly in any engine, well, except for Cryengine naturally

That would be great for livefeed security cams

I compile your code , but failed in "$texture_1". can upload sample project???

Only a fraction of that code was related to render to texture. Im sure he made changes to the renderer to make it work in CE.
