ILLUSION's own version of Valve's RenderTarget
A demonstration of ILLUSION's interpretation of the RenderTarget feature from Valve's Source Engine, found within CharaStudio that is commonly found in Koikatsu and HoneySelect.
You may have seen plenty of H art made with either Koikatsu or HoneySelect, and you notice that there are certain items used which project camera views on screens on those objects, and you've been wondering how all of this was acheived. Well, this right here is the answer.
With the use of the Camera and Monitor items created by user [cz], you can replicate the RenderTarget feature in CharaStudio all by yourself.
I think ILLGAMES' identical equivalent of the CharaStudio found in their titles called Digital Craft may have that too, but I haven't found any videos showcased. But given the overall popularity of ILLGAMES' titles being rather lacking in comparison to those from ILLUSION, I suppose it will remain that way.
Besides, there's a reason people still continue to use Koikatsu to make 3D anime art and animations, NSFW or otherwise.
