Care to give us two pair of eyes? Haha.

I get that a lot.

Couple code edits I'd suggest:

GrassVertOut GrassVS( GrassVertIn IN ) {GrassVertOut OUT;OUT.texcoords = IN.texcoords;//Animate grassfloat4 worldpos = mul(IN.pos, world);//distance to grass for rangefloat gdist = length(worldpos.xyz - EyePos.xyz);float height = clamp(IN.pos.z, 0, 100) / 100;float2 wind = WindVec * 2.5 + 0.25;float2 pos_ticks1 = worldpos.xy / 1000 + ticks;float2 pos_ticks2 = worldpos.xy / 750 + ticks * 2;float2 pos_ticks3 = worldpos.xy / 500 + ticks * 3;float2 pos_ticks4 = worldpos.xy / 200 + ticks * 4;//grass offset for bendingfloat2 bend_ticks1 = (worldpos.xy - EyePos.xy)/1000 * 1/gdist;//interactive grassif ( gdist < 100 ) {	//bend	worldpos.xy += (cos(bend_ticks1)) * height * (1/gdist) * 3500;} else {	worldpos.xy += ( sin(pos_ticks1) + cos(pos_ticks2) + sin(pos_ticks3) + cos(pos_ticks4) ) * height * wind * 10;}

Instead of removing the wind effect, just don't apply it. But, why would wind not be applied? You could cut it down somewhat, but I don't see why you're removing it completely.

I wanted to control it alone, I was thinking "after getting the effect I want I will reapply it back.".

Any progress on this?

Lol, look who's talking. I guess I should be one of the guys to make progress haha.

Mireneye. :shakehead: And I was waiting for you!

Well, above code is giving a good effect,

as you make the initial step, grass offsets suddenly,
as you weight on your step, grass crushes under your feet more.

And since you're stepping on it, wind can't shake it.

It can't get more realistic than this.

Does it still only bend in one direction tho?

Nope!

But the problem is you can't see it since it is only working in first person.

I used the same trick on phal's wavy waters, I am making waves around me. I feel like Moses.

With some programming I assume we can get something better than old water's distortion effects. Addition of player position(s) and some MGE programming for storing previous frame(s) direction and velocity info(accumulation buffers?), it seems very possible to me...

Interesting =)

I'm happy that I helped spawn some wicked ideas.

Any progress with this? The water shader is doing a fine job displacing around the player in 3rd person. What about grass? :3 Seems as though everything is now in MGE to make this happen.

Is this Project dead?

Or are people really working on it in the MGE team?

I think so too. :tops:


I don't think it is dead. But it is possible no one is working on it, I'm not. Should I be working on it? I'm not an advanced programmer. The positioning of grass blades makes it harder to bend them correctly. Maybe just scaling can work instead of bending.

Yes you should! I saw your youtube video, looked just like crysis, though you did mention you hadn't gotten 3rd person to work yet.

If you've got the time and the will, I say go for it. Either way, I'm sure this would be an incredibly popular shader.

Either way, is there a version of this in this thread that works in 1st person? If so, which version is it and what do I have to do to ingame.fx to apply it?

In Phal's latest beta version of MGE, you can call PlayerPos instead of EyePos, which with a bit of modification and tweaking makes the code posted by Peachykeen on page 2 work both in third person and first person. Here's what I put in my InGame.fx file, it works pretty well for me, even though the grass can get somewhat jerky.

	GrassVertOut GrassVS (GrassVertIn IN) {	GrassVertOut OUT;	OUT.texcoords = IN.texcoords;	// Animate grass	float4 worldpos = mul (IN.pos, world);	//distance to grass for range	float gdist = length(worldpos.xy - PlayerPos.xy);	float height = clamp (IN.pos.z, 0, 100) / 100;	float2 wind = WindVec * 2.5 + 0.25;	float2 pos_ticks1 = worldpos.xy / 1000 + ticks;	float2 pos_ticks2 = worldpos.xy / 750 + ticks * 2;	float2 pos_ticks3 = worldpos.xy / 500 + ticks * 3;	float2 pos_ticks4 = worldpos.xy / 200 + ticks * 4;	//grass offset for bending	float2 bend_ticks1 = (worldpos.xy - PlayerPos.xy)/1000 * 1/gdist;	//interactive grassif ( gdist < 100 ) {	//bend	worldpos.xy += (bend_ticks1)/abs(bend_ticks1)*(cos(bend_ticks1)) * height * 1/(25+gdist) * 3500;} else {	worldpos.xy += ( sin(pos_ticks1) + cos(pos_ticks2) + sin(pos_ticks3) + cos(pos_ticks4) ) * height * wind * 10;}

edit: here's a video of it http://www.youtube.com/watch?v=HjqFOvYOUVI

Very vice tomerk!

Any FPS hit?

I don't think i'd use it since i tend to play in first person and it wouldnt really be that noticeable.

thats awesome iv been waiting for this, so do i just edit the ingame like shown to get this function or are there scripts to add also???

Didn't work for me, i just pasted it last in ingame.fx. All i got was a kind of stuttering grass.

Find this section of code in the .ini file

GrassVertOut GrassVS (GrassVertIn IN) {	GrassVertOut OUT;	OUT.texcoords = IN.texcoords;

now look at his code, add only his changes into that section of code.

however, I just tried doing this myself and it causes mge to suggest that the ingame.fx file is unreadable, I'm not exactly sure why.........give me a few minutes and I'll see if I can figure it out.

okay everytime i add the new bit of code to the ingame morrowind can no longer load the distantland effects so not water grass or shaders anything, any reason it might do this im using phals mge beta v5

awersume

@tomerk
Very nice video tomerk. It appears to be working better than I expect. :foodndrink:




You have to be careful, only one mistake will cause an error. Try to maintain the order and apply it to correct places.

well i copyed and pasted what was put on here, i dont see what i might have done wrong
heres section of my ingame with the grassvertout in the middle ish

// Projection
OUT.pos = mul (worldpos, view);
OUT.pos = mul (OUT.pos, proj);

// Lighting
OUT.color = (SunCol * 0.25) + SunAmb;

return OUT;
}

is this right?

There are 4 intances of grass code.

Search for

//Animate grass

there is a line

float4 worldpos = mul (IN.pos, world);

in 2 of those 4 instances.
Move this line above "//animate grass" line.

Then it will look like this, all 4 instances:

//Animate grass		float height = clamp(IN.pos.z, 0, 100) / 100;		float2 wind = WindVec * 2.5 + 0.25;			float2 pos_ticks1 = worldpos.xy / 1000 + ticks;	float2 pos_ticks2 = worldpos.xy / 750 + ticks * 2;	float2 pos_ticks3 = worldpos.xy / 500 + ticks * 3;	float2 pos_ticks4 = worldpos.xy / 200 + ticks * 4;		worldpos.xy += ( sin(pos_ticks1) + cos(pos_ticks2) + sin(pos_ticks3) + cos(pos_ticks4) ) * height * wind * 10;

then change that part with

// Animate grass		//distance to grass for range	float gdist = length(worldpos.xy - PlayerPos.xy);	float height = clamp (IN.pos.z, 0, 100) / 100;	float2 wind = WindVec * 2.5 + 0.25;	float2 pos_ticks1 = worldpos.xy / 1000 + ticks;	float2 pos_ticks2 = worldpos.xy / 750 + ticks * 2;	float2 pos_ticks3 = worldpos.xy / 500 + ticks * 3;	float2 pos_ticks4 = worldpos.xy / 200 + ticks * 4;	//grass offset for bending	float2 bend_ticks1 = (worldpos.xy - PlayerPos.xy)/1000 * 1/gdist;	//interactive grassif ( gdist < 100 ) {	//bend	worldpos.xy += (bend_ticks1)/abs(bend_ticks1)*(cos(bend_ticks1)) * height * 1/(25+gdist) * 3500;} else {	worldpos.xy += ( sin(pos_ticks1) + cos(pos_ticks2) + sin(pos_ticks3) + cos(pos_ticks4) ) * height * wind * 10;}
