Did you try this with out of core feature being turned on or off? I think with out of core there shouldn’t be much difference between TX and more traditional file formats if at all, because to my knowledge Corona is converting textures to TX internally.
Hi,
The .tx is used in cosmos models because it includes mimapping ( use different resolutions of the texture depending on its size in the final image). This results in significant memory savings and improved rendering speed. While Corona has its own out-of-core rendering for textures, the support for .TX format was provided to ensure compatibility of cosmos models across all chaos products, not just Corona.
In Corona, all textures benefit from Out-of-core rendering as it unloads the memory used by textures to hard drive by using a lower resolution version of them, depending on how far from the camera they appear in the scene.
Thanks, it makes a lot of sense but, honestly, given the power of nowdays cpus and the available amount of RAM in today workstations, I don’t really feel the need for it, especially as it creates a new step in the workflow in term of editing the textures, as .TX files aren’t directly editable in PS. So it’s unlikely I will start using this format, unless the rendering speed gain is significant.
What is the average rendering speed gain?
just in case somebody wants to create tx format image you can do that easily with this tool from OpenImageIO.
this will convert images to tiled, MIP-mapped textures (tx format)
it would be better to add its folder to user variable PATH in windows system environment to make system-wide accessible.
this has many options and it is indeed a great tool.
you may also find this in Arnold and V-Ray plugin folder for 3dsMax

hello, i have read all thats written here, i understand the benefits of tx files but it should have the option to have somewhere all the maps as jpg. in my workflow i never had the need for more ram. for example if i want to edit a material and change its appearance, its easier with a jpg to get the map i want. the utility of the materials is mostly if you start from them and make your personalized ones, considering the cosmos is very limited (look at wood for example, almost never i havent had the colours i needed for my projects). so, in conclusion, what is the easiest way, what program do you use just for opening a *tx file and save it to a more usable format ? thank you
