Projecting pattern to object with light - Developers

So basically I want to make a lighting which projects patterns to an object. I don't know how to say it in words, I'll give you picture instead. [IMG]http://www.adweek.com/files/adfreak/bathroom.jpg[/IMG] How can I achieve that kind of lighting in Source?

I think what you need is an env_projectedtexture entity. [url]https://developer.valvesoftware.com/wiki/Env_projectedtexture[/url]

By the way, does Source 2009 Hammer tools support this entity? Or I should use Portal 2 authoring Hammer?

Yeah, Source 2009 works, so does Portal 2.

Thanks for the input guys. Really appreciate it. I just realized Garry's Mod does not support dynamic shadow on my laptop. I've read Shadow Details need to set to "High" to make env_projectedtexture to work, but I only have "Low" and "Medium" in Shadow settings dialogue. It's weird that the engine capped my GPU capability that way, while I can see my laptop can support Portal 2 dynamic shadows. Seems like I need to use Portal 2 engine :/ Note: I'm using Intel GMA 4500MHD. Yeah I know crappy card :P

I think also the gpu options can unlock some extra stuff. I was limited to horribly low textures but then I changed the graphics card settings to allow higher res.

Tweaking my GPU options to maxed doesn't help either. [IMG]http://puu.sh/mlm6[/IMG] However it does works with Portal 2 engine. [IMG]http://puu.sh/mllG[/IMG]

Source pretty much hates onboard intel chips. In fact most games and probably most compat testers hate onboard intels.

[QUOTE=IronPhoenix;35291363]Source pretty much hates onboard intel chips. In fact most games and probably most compat testers hate onboard intels.[/QUOTE] Source still runs amazingly though comparing to other engine. Yep, this is my fate, with this Intel chips.

Well I need some assistance. I attempted to create my own texture to be projected by the light, but seems I missing something here. [IMG]http://puu.sh/msoW[/IMG] Probably it's my VMT/VTF config, I would be glad if anyone can help :) EDIT: Oh, finally just figured that out by some change in VMT settings and VMT format.

Did you use $alphatest instead of $transcluent?
