It is possible somehow to blend 2 textures without using a .fx file?How?Can you pls give me some good tutorials about this topic?

Hi there Zmax,
How are you doing?

The Problem
Sure you can, Texture blending.

The Solution
You can check out this resource in the SDK.
Texture Blending


I hope this helps buddy.

Hi i don't know what to write in the last parameter of the
dev->SetTextureStageState( i, D3DTSS_COLOROP, WHAT IS THIS?); ...
this is how i use 2 textures trying to blend them:

device.SetTexture(0, VertexCls.Texture(0))
device.SetTextureStageState(0, TextureStageStates.ColorOperation, 1)
device.SetTextureStageState(0, TextureStageStates.ColorArgument1, 2)
device.SetTextureStageState(0, TextureStageStates.ColorArgument2, 3)

device.SetTexture(1, VertexCls.Texture(1))
device.SetTextureStageState(1, TextureStageStates.AlphaOperation, 1)
device.SetTextureStageState(1, TextureStageStates.AlphaArgument1, 2)
device.SetTextureStageState(1, TextureStageStates.AlphaArgument2, 3)
do i have to use a special material in on the vertxes, what type ? normaltextured,coloredtextured,positiontextured...i use now positiontextured,..it works for texture blending?

A,...actuly now my shape is complete white...hmm, why?

I want to texturate it only in some specific places with blend, and in the rest normal textured with one texture...


P.S I used this too but no positive effect:

Dim x As TextureArgument
Dim y As TextureOperation

device.SetTexture(0, VertexCls.Texture(0))
device.SetTextureStageState(0, TextureStageStates.ColorOperation, y.Add)
device.SetTextureStageState(0, TextureStageStates.ColorArgument1, x.TextureColor)
device.SetTextureStageState(0, TextureStageStates.ColorArgument2, x.Diffuse)

device.SetTexture(1, VertexCls.Texture(1))
device.SetTextureStageState(1, TextureStageStates.AlphaOperation, y.AddSmooth)
device.SetTextureStageState(1, TextureStageStates.AlphaArgument1, x.TextureColor)
device.SetTextureStageState(1, TextureStageStates.AlphaArgument2, x.Diffuse

ok, im a bit hazy on this, but i think its how you want the textures to blend( or not to blend ). in fact to quote to docs:

Quote:
D3DTSS_COLOROP
Texture-stage state is a texture color blending operation identified by one member of the D3DTEXTUREOP enumerated type. The default value for the first texture stage (stage 0) is D3DTOP_MODULATE; for all other stages the default is D3DTOP_DISABLE.

it really depends on how you want the textures to blend together. do a serch for D3DTEXTUREOP in the DX help file to find out what they all do.
