Foliage fade out over distance

(Madras) #1

Hi,
I added foliage to my map by the shader but I have a problem because foliage fade out over distance.
How to increase draw distance of the foliage?
Thanx for help ;D

Border of drawing:

Foliage part of shader:

textures/depot/lmterrain2_base
{
	q3map_normalimage textures/sd_bumpmaps/normalmap_terrain.tga
	
	q3map_lightmapsize 512 512
	q3map_lightmapMergable
	q3map_lightmapaxis z
	
	q3map_tcGen ivector ( 512 0 0 ) ( 0 512 0 )
	q3map_tcMod scale 2 2
	q3map_tcMod rotate 37
}

textures/depot/lmterrain2_foliage_base
{
	q3map_baseShader textures/depot/lmterrain2_base

//	q3map_foliage <model> <scale> <density> <odds> <use inverse alpha>
	q3map_foliage models/foliage/grassfoliage1.md3 1.25 48 0.1 2
	q3map_foliage models/foliage/grassfoliage2.md3 1.1 48 0.1 2
	q3map_foliage models/foliage/grassfoliage3.md3 1 48 0.1 2
}

[…]

textures/depot/lmterrain2_1
{
	q3map_baseshader textures/depot/lmterrain2_foliage_base
	surfaceparm gravelsteps
	surfaceparm landmine

	{
		map textures/stone/mxrock1b.tga
		rgbgen identity
	}
	{
		lightmap $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
		rgbgen identity
	}
}

It is the distancecull line on the foliage model’s shader. Do not edit the original file. Make a new shader for it.

A bit offtopic, but I noticed “normalmap_terrain.tga”
I hope its not bumpmapping you are talking about…

I wrote shader with distanceCull line, but it doesnt work :((
Any ideas?

textures/depot/lmterrain2_foliage_base
{
	q3map_baseShader textures/depot/lmterrain2_base

	[B]distanceCull 8192 8192 0.4[/B]

//	q3map_foliage <model> <scale> <density> <odds> <use inverse alpha>
	q3map_foliage models/foliage/grassfoliage1.md3 1.25 48 0.1 2
	q3map_foliage models/foliage/grassfoliage2.md3 1.1 48 0.1 2
	q3map_foliage models/foliage/grassfoliage3.md3 1 48 0.1 2
}

I’m working on the same thing ATM.

The shader you want is “etmain/scripts/models_foliage.shader”

Look for the “models/foliage/grassfoliage1” , “models/foliage/grassfoliage2”, “models/foliage/grassfoliage3” sections.

Remember to put the modified shaders in your own shader file, leave the original ones alone.

ok but how to deploy foliage on my own map without using models?

I have own models and I want to increase draw distance of foliage…
So what I must modify in this shader to enlarge distance.

textures/depot/lmterrain2_foliage_base
{
	q3map_baseShader textures/depot/lmterrain2_base

//	q3map_foliage <model> <scale> <density> <odds> <use inverse alpha>
	q3map_foliage models/foliage/grassfoliage1.md3 1.25 48 0.1 2
	q3map_foliage models/foliage/grassfoliage2.md3 1.1 48 0.1 2
	q3map_foliage models/foliage/grassfoliage3.md3 1 48 0.1 2
}

Sorry for my bad English

Nothing in this shader. Go to the shader of the actual grass models! (models/foliage/grassfoliage1…). From there you will find distancecull command which you are supposed to edit. Do note that making the draw distance too far can kill your fps.

It works! Now game draw very far grass and fps looks great :stuck_out_tongue:
Thank you very much for helping! :smiley:
