Render Blobs - Hidden Particle Editor Element
So I was looking into how the gel-like blobs on Rubick's staff were made and when I opened up the decompiled particle in the editor I saw this:
It's not in the render list when you try to add it manually, so it seems this is a hidden element in the editor. Here's the options it comes with:
Playing around with it, I found it's a very powerful method to render thick gooey materials, almost identical to the gel in Portal 2. Here's what it looks like:
The above pic is with a black material and a yellow glow-sprite so you can see the 3D easier.
There's also a few catches I've noticed that make it different from ordinary particle render types:
- Blobs do not obey the particle's radius or colour setting, but you CAN set their material
- Blobs cannot use most textures, but they should render any texture that shows up when you search 'blob'
- Blobs take a control point as their size, and will not show at their default [0,0,0] size; so this must be preset
- Blobs' scale control point is not [SizeX,SizeY,SizeZ] and acts strange if X, Y and Z are not kept equal
- Blobs can be made more detailed by lowering the cube width value, or the scale control point's X value
- The render radius and the CP's Z value set the blob's radius, but all other values should be kept proportionate
- Changing or removing the 'lifetime random' element causes the blobs to act rigid and slow after a few seconds
I've prepared a download link for a base particle if anyone wants it, since there doesn't seem to be any other way to use it.
Anyone think there's anything else hidden in the editor we could find?
EDIT: Found some more info on it's usable textures; it fails to render anything complex like transparency or masks, but it can handle most-anything flat. There are also a few materials it can use with reflectivity, such as that used for Jakiro's Ice Path. There is also an ugly-purple texture for oil and a seemingly broken (yet working) scrolling texture for water. Just search 'blob' under materials.
