new fur code(grass)

(pazur) #1

i`ve added alphagen vertex to 2nd stage of the blend terrain shader(1to2 etc). my fur grass still looks like it has 1 layer with .36

ydnar. could u plz go quickly through the shader to tell me why my fur looks so different with .36? and what to add or remove to make it work with .36 . thanks in advance

(ydnar) #3

Post screenshots. I cannot divine what you are talking about from the shader alone.

ok. here we go:

i hope u see the difference

I don’t see any difference in the grass.

What’s with the door ent in the 3rd screenshot? What compiled it correctly before?

(pazur) #6

the door is something different. i solved that problem already(brush cleanup helped there)

format: q3map_fur <layers> <offset> <fade>

i have: q3map_fur 6 2 0.15

so 6 layers. with .36 it looks like 1 layer

edit: better screenshots with white tex behind the grass :slight_smile:

Does it ever look higher on areas where the terrain is completely made up of the grass shader? I made a change to the fur code where the original vertex alpha would fade the distance the fur stuck out from the surface.

Just checked the code again. It seems it’s offsetting each fur layer off the initial layer, as opposed to the previous layer, which is why you only see two layers of fur.

This bug will be fixed in the next release.
