I was just wondering if anyone on this site has any tips and tricks on how to create a realistic grass scene in lightwave?, bearing in mind i don't currently have LW11 so instancing is not an option.

Instancing is an option if you download DP-instance. There's also a cool technique using clip maps. The clip map scene is here somewhere on the forums.

particles with sprites might work as well, but from previous experience was rather difficult to pull off in LW.

regarding clip maps, i think instancing should be just as fast...?
(and flicker less) (p.s. > pump up the ray trace limit if using clips...)

That works.

This is the clipmap option ... think that's what 3DGFXStudios is referring to:thumbsup:

very important are different textures and grass length for creating realistic grass.

model round grass patches, not to big, every patch with different grass length/type
model ground grass which is bend to the ground and has a dirty or not so green texture
model small, medium and tall grass patches with different textures
thatīs a really cool tutorila on grass - http://thenatureacademy.blenderguru.com/fe/18406-realistic-grass-tutorial

then fire up instancer and put all the different grass types in it.

for the environment and lighting try the sunsky plugin from dpont.

how many instances you need depends on the angle you look at the grass, from top you need more instances, i hope you understand what i mean :)
als helpfull is a gound grass with dirt ground texture.

i hope i could help you

Wow thanks for replies. All these tips sound promising. The Blender tutorial seems the most promising to me, provided i can export the scene into LW. If not maybe a mixture of instance and sprites might do the trick :)

I will post up my progress on the scene when I'm home.

note, Lightwave has SoftFX so you should be able to replicate the Blender setup :]
