here is the 2011 scene

i downloaded your scene and the problem is there too, you gotta activate final gather, thats what i did with your scene, set gamma 2.2 in exposure shader and f-stop at 8 to see better.
it seems it has some problem with FG?
i'm uploading my scene in a moment

The problem seems to be with the grass normals looking on the wrong side :
' WARNING : RCFG 0.6 warn 542002: angle between normal and geometry normal > 90 degrees

the only solution i found is setting the Mode to "Expert"
and the "Filter Size = 0"

oh thats fine, i use expert with 0 0 quite often for exteriors, so it should work

i'll check it in a bit

ok reconnect node bend strands after self strand size and color and it work! strange

did anyone try to create animated grass with this compound?

When I set the Attribute_Color to StrandColor it is not bend, but when it is set to Color, The blades are bended. I do not understant why tweaking the render_tree changes the shape of the blades?

I tried to reconnect the node bend strands before self strand size and color, as it was connected after, and I have bended blades again but no more color.

I am using Softimage 9.5 64 bit (2011 Subscription Advantage...)

Hallo

Anyone knows how can I use a texture to color the grass made with this compound?

Hirazi Blue · Post by **Hirazi Blue** » 22 Jun 2011, 13:57

Do you mean texturing individual strands along their length?

Ramon · Post by **Ramon** » 05 Jul 2011, 11:07

NOT work in SI 2012 SP1
what wrong in strands compound? what change from 2011?

The new (V1.1) Randomize around Value compound has a Scalar node in place of V1.0's pass_through node, letting it not accept arrays or vectors as inputs anymore.

Go into the compound and switch all Randomize around Value compound versions back to 1.0, then it should work as usual.

Probably a bug introduced in 2011SAP, since the "Variance" parameter is also named "Value1" in the compound, which is unusal for factory compounds.

Hey I'm having small problem with this

Sample scene works perfectly in SI2012. everything as it should be.
But when I try to create my own grid with grass, Create Grass compound is always red.
Am I mising something or?
Again, imported sample scene works fine.
Any ideas?

Ramon · Post by **Ramon** » 22 Aug 2011, 07:01

You must change some nodes in compound! see post above!

mirkoj · Post by **mirkoj** » 22 Aug 2011, 08:12

ugh. mental note, read read read before post.
sorry got it!

unfortunately there is a huge amount of grass needed and ram goes over the roof!
my 8gb is not nearly enough and fur goes a bit under that so I will probably have to settle with fur

but thanks!
