Hey Aoktar, another question regarding Vram usage.aoktar wrote:Thanks. For additional info about how Octane works with images: It has some optimisations to avoid more vram usage. Ex. if you use a image at different slots, will only use one copy of this image. But if you use it with different mode, ex. "Float" and "Normal". This will cause to create a additional copy. This valid for direct access to images by the paths. But if we register them by ram buffer method, each copy will spend extra vram. When we use buffer system? With C4D shaders->render textures or using the layers of some PSDs. I hope that's not so much confusing.ralf_breninek wrote:Great tool to improve your scene performance and finding problems easier, thanks Ahmet
Seomething I find strange is that some images are listed multiple times, like in the middle of the first screenshot "yol.tif" I do not think that this single image really takes up 135mb of VRAM only because it has been used three times, or does it? If it only uses 45mb listing it only once might be enough maybe, or is there another reason to show it several times then?
You say if the mode (Normal - Float) is different, then the image has to be put twice into vram and size increases. Now my question: Does it also depend on the gamma and power values? So an image in a slot with a gamma of 1 and the same image in another slot where it uses a gamma of 2, does octane only use one in VRAM or two images?
For example I have this one tex, which is pretty big, and its always used in normal mode, however, with different power and gamma settings. Is this put into vram only once or dozens of times like its visible here? Would it be better to use a color correction node instead?
