Can someone please tell me how I can save a bitmap file after editing it with the pixel_to_bmap function?

Don't tell me it's impossible. If it is, how can I use the edited bitmap as a texture for an effect after it has been edited? Is it supposed to work?

Thanks in advance.

How about you post this in the "future" forum.
saving bitmaps to a file.

I dont know of any direct method.

You could display the bitmap on the screen and generate a
(bmp) screenshot... as a simple workaround.

I'd say it *should* be possible with render to texture somehow, but I've never tried it, so I'm not sure.

Cheers

if you are just going to use it in an effect.. in fact it should be ready to use with no problems.. what happens when you try it?

There is no difference on my terrain, where I use it as a blendmap, I'll check it again, but I've even added a wait between the edit and then it starts applying the material a few frames after it has been edited

i added a tga writing script to the wiki a while ago but for using a modified bitmap in an effect, saving and reloading shouldn't be necessary actually.

Could you give me a tutorial or example script to do it without saving, I just want to compare it with my own. Otherwise I'll see if I can incorporate that tga writing script. Thanks for the replys.

Did you make sure to unlock it after you are done writing to it?

Yes, Heres a piece of my code:

format = bmap_lock(blendmaph,0);
y=0;
x=0;
while(y<40)
{
while(x<40)
{
temp=(heightmap[((x)*400)+y]/255)*100;
pixel = pixel_for_vec(vector(temp,temp,temp),100,format);
pixel_to_bmap(blendmaph,x,y,pixel);
x+=1;
}
x=0;
y+=1;
}
bmap_unlock(blendmaph);

This is run just before applying the material effect to my terrain. The blendmap is a tga file. I have checked that it actually works by setting the bmap up as a panel and it does what I want it to do, but there is no difference as blendmap in effect.

Indeed, setting it up as a panel is the usual test to check whether a bitmap is correctly written. If it's visible in a panel, it also looks the same when you use it as a model or terrain texture.

So the problem is somewhere else, like using the wrong bitmap for your effect. Another possibility is when the bitmap is converted to a normal map or uv map etc, which of course alters it totally.

Saving a bitmap is implemented in the beta version and is in experimental state currently.
