I think there is a possible bug in the implementation of the compressed texture array, although I may just be missing something. I have created compressed versions of my textures. However, when I set my engine to use them, I get an error finding the compressed version of the environment.dds file. `babylon.js:16 BJS - [15:47:13]: e failed when trying to load https://www.babylonjs-playground.com/textures/environment.dds, falling back to the next supported loader` It’s looking for this: [https://www.babylonjs-playground.com/textures/environment-dxt.ktx](https://www.babylonjs-playground.com/textures/environment-dxt.ktx) Instead of this: [https://www.babylonjs-playground.com/textures/environment.dds](https://www.babylonjs-playground.com/textures/environment.dds) Is there a way to exclude certain files or file types from the `setTextureFormatToUse` method? ETA: Here’s a Playground in which you can see the issue.

Unfortunately you once you set the engine to use ktx it is expecting to use it for all textures at the moment. @Deltakosh should we smthg to autorize excluding some format to be checked as ktx ??? ---

Yeah, when I did ktx, I don’t think there even was an environment texture. Babylon.js is now a little too complicated for me to work directly in Engine. Loading environment first should go through, blissfully unaware of what is to come. ---

Oh yeah that is a nice one 🙂 just call setTextureFormat after creating the env 🙂 I love it !!! ---

I see! For some reason that wasn’t working for me but maybe I was just not paying close enough attention. But can you point me in the direction of where that code lives? I wonder if I can take a stab at it by adding an exclusion array? ---

right here: [Babylon.js/thinEngine.ts at master · BabylonJS/Babylon.js · GitHub](https://github.com/BabylonJS/Babylon.js/blob/master/src/Engines/thinEngine.ts#L2663) You could add a global exclusion list as well ? ---

Yeah, I’ve got it working. Just figuring out how to get all the linting and tests to pass. Hopefully I’ll have a PR ready this weekend 🙂 ---

Nice !!! The easiest to run tests and so on is to create a PR so that we could help you with your errors if needed 🙂 ---

Thanks, it’s passing all tests now, but when I run it in the local test bed it doesn’t see a new method I’ve created. I assume that’s because the d.ts files aren’t being updated somehow? ---

that is strange it should all work if you do npm run build from the tools/gulp folder as it updates the .d.ts before going through the tests. If you do this, please do not add the dist/\* files as part of your PR 🙂 ---

Yeah, this code works: ```auto var available = ['-astc.ktx', '-dxt.ktx', '-pvrtc.ktx', '-etc1.ktx', '-etc2.ktx']; var formatUsed = engine.setTextureFormatToUse(available); engine['setCompressedTextureExclusions'](['.dds']); ``` So the method is there, it just doesn’t see it in the editor. ---

oh in the editor this is possible, you should try to create the PR and we ll be able to look into it ---

First pass at the PR. All suggestions for improvements are very welcome! > Also, I’m not sure why there are formatting changes. Maybe my fork got outdated by a recent commit? ---

@sebavan thanks for helping me! Now that we’ve merged, should I see that method on the Playground? It’s in the master branch but the editor throws an error when I try and use it. ---
