View Full Version : Special Buffers?
09-19-2002, 03:52 PM
Hey all :)
Okay, how many of you have ever used the Special Buffers in the Surface Editor?
I know how they work, and what they do, and I've used them before, and set them up correctly and all that, but I never seem to see much (if any) of a difference...
Has anybody got any tips for using them?
It should be a really useful tool, and I'm keen to find out how to utilise it better.

We use it alot to do masking and create different alphas in one render pass. Also, some of the cooler image filter plugins allow you to use them as masks as well (bloom, corona)
The only problem i have with the special buffers is that there seems to be just one, even though you have 4 special buffer inputs.

Yeah - that's exactly what I've noticed too! Even though they are supposed to work with 4 slots, the ones after 1 don't seem to have a effect.
I think I will investigate this further :)

Guys did u read the manual?
The slots of special buffer is for image filters slotted under Image process -> Add image Filter. Here is the example:
I used special buffer 1 - 100% and first image filter was corona with impute channel - Specular shading and Threshold Mask - Special buffer
special buffer 2 - 60% and second image filter is Full Precision Blur with Use Mask option - Special Surface (i don't know why this option called Special Surface instead Special Buffer).
U can see the difference on attached picture - the upper image use Special buffer for second filter and lower not.
I found that only few filters can use the Special buffer - Corona, FP Blur, Photoshop PSD Export, Soften reflection - funny but it's only four! Now i understand why Special Buffer have only 4 slots :)

Aaah that makes sense :)
As I said, I know what it is, but I just hadn't seen any major differences before :)

hehehe cool :thumbsup:
I can't believe I never realised the correlation between the fact that there were only 4 slots, and only 4 buffers that worked with it :blush: hehehehe so thanks for pointing that out ;)
