Hi, How to check if a file exists, using TypeScript? So far I did: Imported File System module via: const fs = require("fs"); This gives error: Module not found: Error: Can't resolve 'fs' in 'C:\Users\user\Documents\project\src' Parsed request is a module using description file: C:\Users\use…

Okey, so you’ve received few ways of solving this issue. As I wrote before you can use: [image] Check if File Exists? Questions Okey, so just keep digging wink You can also try to use BABYLON.Tools.LoadImage like in here: Or you can do it by using plain JS […

fs is NodeJS function, and it is not available in the browser. What do you want to achieve? Why do you need to check if the file exists in the browser?

Thanks for the explanation. I want to load and assign a texture. But I cannot be sure it exists. var texture = new BABYLON.Texture("some/texture/path.jpg", scene) as BABYLON.Texture; ... block.texture = texture; I thought I could check if the file exists before attempting it to be casted as a Tex…

Okey, so first thing is that the Texture is trying to get the file via XHR (async) request. If it fails you will see the error in the console. So that is why nothing breaks (it’s async) and the app is still running. Second thing is that you can use OnTextureLoadErrorObservable method to get notifie…

Thank you. However, how to assign the texture when the loading succeeded? Your referenced playground just checks if any texture loading failis. BABYLON.Texture.OnTextureLoadErrorObservable.add(e => { console.log('err', e.name); });

I may be not the best person to ask this because I don’t really work with textures. But IMO you can choose from two strategies: assign the textures as you did before and observe on the errors - if there are errors - act. Let’s call it that we assume the positive case. var texture = new BABYLON.T…

I found something, that seems on the correct path, but the author also states it is a bit of a hack. [image] BaseTexture.WhenAllReady returns too early beetleBugs When using BaseTexture.WhenAllReady to wait for the ready state of a texture which has just been a…

Okey, so just keep digging :wink: You can also try to use BABYLON.Tools.LoadImage like in here: [image] Tools.LoadImage() can't load KTX2 file Questions Hello! I want to load KTX2 texture file using Tools.LoadImage() but it keeps returning Error while trying to load image…

I never found a solution to this. Though I did other mistake, I assumed I am checking something that I am not. let blockInShader = cloneMat.getBlockByName(matchedBlockName) as BABYLON.TextureBlock; I incorrectly assuming I should check for a texture: if (blockInShader.texture) While I should h…

Good that you’re moving forward! [image] lauris47: How do I do that with Vector4/Color4 and float values? Could you be more specific? How do you do what with Vector4/Color4?

I think this goes a bit of topic, so I am continuing here: [image] Set parameters as texture or color in NodeMaterial via code Questions Thank you, that worked. var property = nodeMaterial.getBlockByName("DiffuseTexture"); var textBlock = property as BABYLON.TextureBlock;…
