Hey, this time i'll need horde3d related support. How to recognize size of buffer (texture resource) returned by h3dMapResStream? Am i forced to remember type of texture i loaded, and then compute it on my own? |

I don't really want to be too annoying, but could someone help? How big buffer, mapped texture buffer is? AFAIK it's not plain RGB/RGBA so i can't simply compute with by width*height*sizeof(rgba). |

As you have the texture resource, you get the texture's width, height, depth and texformat. Then you have to replicate RenderDevice::calcTextureSize in your own code (as there is no way of getting the size directly from the API) and feed it with the texture's dimensions and type. Yes, some kind of API for that would be nice. |
