Unity3D to Babylon Exporter and skybox/cubemaps...

[exc_html5]

Howdy Babylonians! 

When I used the unity3d to babylon exporter it currently takes my cubemap and exports it out to a series of JPGs for the different faces of the cubemap. I would like to have use PNG files instead. I can fix this on the exporter side fairly easily by switching the command to from 

File.WriteAllBytes(faceTexturePath, tempTexture.EncodeToJPG());

to 

File.WriteAllBytes(faceTexturePath, tempTexture.EncodeToPNG());

and then also changing the output naming convetion from

  case CubemapFace.NegativeZ:
                            faceTexturePath += "_nz.jpg";

to 

  case CubemapFace.NegativeZ:
                            faceTexturePath += "_nz.png";

When I change these it makes the PNG and names them correctly, but the exported BJS scene doesn't read in the reflection textures correctly. Here is what it looks like when I export the JPG version:

- 

What it looks like when I switch everything over to PNGs 

- 

When I load the scene into the babylon sandbox it says " [15:15:49]: Error while trying to load texture: file:ReflectionProbe-0_pz.jpg "

So it's still looking for the jpgs insted of the PNGs. Here are the settings for the shader:

{
			"name" : "babylonjs_sample_material_reflection",
			"id" : "fb8dec12-8352-4e22-8ec5-83008b1780c1",
			"backFaceCulling" : true,
			"wireframe" : false,
			"ambient" : [1, 1, 1],
			"diffuse" : [0, 0, 0, 1],
			"specular" : [1, 1, 1, 1],
			"emissive" : [0, 0, 0, 1],
			"specularPower" : 53.588665,
			"alpha" : 1,
			"diffuseTexture" : null,
			"diffuseFresnelParameters" : null,
			"ambientTexture" : null,
			"opacityTexture" : null,
			"opacityFresnelParameters" : null,
			"reflectionTexture" : {
				"name" : "ReflectionProbe-0",
				"level" : 1,
				"hasAlpha" : false,
				"getAlphaFromRGB" : false,
				"coordinatesMode" : 3,
				"isCube" : true,
				"uOffset" : 0,
				"vOffset" : 0,
				"uScale" : 1,
				"vScale" : 1,
				"uAng" : 0,
				"vAng" : 0,
				"wAng" : 0,
				"wrapU" : 1,
				"wrapV" : 1,
				"coordinatesIndex" : 0,
				"isRenderTarget" : false,
				"renderTargetSize" : 0,
				"mirrorPlane" : null,
				"renderList" : null,
				"animations" : null
			},
			"reflectionFresnelParameters" : null,
			"emissiveTexture" : null,
			"emissiveFresnelParameters" : null,
			"specularTexture" : null,
			"bumpTexture" : null
		}

Is there a way I can adjust the unity exporter code to have it look for the PNGs that were created instead? Or if not is there a way to alter the shader settings after the fact to have it look for the PNGs?

Hey!

unfortunately we try to load jpg only by default:

https://github.com/BabylonJS/Babylon.js/blob/master/src/Materials/Textures/babylon.cubeTexture.ts#L32

BUT there is a good news

You can add the extensions you want to use in the .babylon file:

https://github.com/BabylonJS/Babylon.js/blob/master/src/Materials/Textures/babylon.cubeTexture.ts#L79

So add a "extensions" property under your reflectionTexture entry in your json file and set its value to: ["_px.png", "_py.png", "_pz.png", "_nx.png", "_ny.png", "_nz.png"]

Thanks! Hopefully that will do the trick!
