physical grass

[Claudio Branch]

Nice claudio - maybe add some yellow/lime glossys?

 

 

Thanks.

 

A good suggestion to make it look a bit more underwatered perhaps...

Deconstructing the Elements has a nice chapter on particles for grass.

 

I hope to do it tonight.

i almost got that. i opted instead for a couple of books on character modeling. how do you like it?

[Mike.]

glad i found a thread about grass. i used a house i'm working on to make a grass test.

i used vray proxies .

Please comment the overall grass look about how you would improve it.

 

Thanks

Your grass is looking pretty good to me!

 

The long grass you have in the foreground is a problem though. It is too straight and uniform. You might try creating a separate grass entity to distribute in the foreground. Give the geometry more variation.

 

Nice image all around...

thanks,

in fact the long grass in the foreground is not grass

its a kind of a bush i wanted to place here to break a bit the ground monotony. Obviously if you thought it was grass, it means i have to change it

though i have a problem whith the grass. the green is not very nice, and the consistency is too fuzzy......i'm trying to make a regular grass, as if it was well treated.

i will try other settings.

Thanks for opening a thread about grass. it's my graal at the moment.

Isn't "fuzzy" a species...

 

It probably is a little fuzzy, but that is an easy fix...

i made a fix in color (more yellow) and consitency(scale of each grass "leaf".).

it's still a litlle fuzzy, and the grass is a bit too long and thin, but i think i 'm on a good path.

Looking good...what kind of mapping scheme are you using?

 

I have been using a Mix map w/ a Noise map for blending the bitmaps. One grass map is a dark forest green grass and the other is bright green grass.

the mat is a simple vray mat, whith some reflect and refract, and as diffuse i use a gradient ramp from dark green to light green, mapped in a way that i have Dark Green for the bottom of the grass leaf, and light green for the high part. there is no "global" mapping. Only a mapping for the grass leaf unit.

What would help to distinguish the grass from the bushes is addinig a bed of multch with possibly edging. As a gardener its a constant battle to keep the grass out of the flower beds

thanks

i like those kind of hints

way more realistic than simply putting bushes on grass.....plus a nice multch can give a nice foreground detail to catch the eye.

Looks great!

[Mike.]

Thanks

 

cheers

here is my last grass try...

thanks to vray meshes . the amount of polys you can manage whith them is incredible.

[blowback]

Mike,

 

I think that's looking pretty good. It may be a little too even, but I like the start.

[Mike.]

It may be a little too even

i wanted it to look even cause it's intended to be a sell picture..... so the grass must be as if it was a healthy well maintained grass. but i'll try a less even distribution to see what comes out. thanks

I like the start.

i know that's just a start and many things to improve, but being in a hurry whith my client i have to stop there whith the grass for this pic... i hope this will look as grass for him....

if it comes out nicely, i'll post my next researches on this thread...

 

Bye

Hey Mike, what did you use to distribute the proxies? I seem to have problems with mine in large numbers, even in box mode. I do have a pretty large area to cover though.

if you're talking about the distribution tool, it's called "object painter". it's part of the of neil blevins script collection...it allows user to 'paints' object (proxies in this case) onto surfaces

i never tried this on large areas.... i usually deal with 3-4 K proxies..

If you're talking of the proxy mode i use, it's box mode, with bounding box general display. i put all proxies in a layer i keep frozen until the render to speed display. sometimes i even save selected my proxies in a separated file, and merge it as Xref at render time only.

HTH.

[Mike.]

you're very welcome
