Do you guys have any plans on text formatting functionality? Being able to have different text styles in one Pixi text object. For example: This is a bold string and an italic string as well as the strikethrough within a single Pixi text object. Also, do you guys plan on adding different orientation support (like vertically oriented text for oriental characters)? Thanks for the great work you guys are doing.

Hello ! As I'm currently playing with some unsigned integer textures, I would love to see BabylonJS support them. I'll do a PR as soon as possible, adding some (all ?) constants about internal formats (for instance Engine.TEXTUREFORMAT_RGBA_INTEGER) and texture types (for instance Engine.TEXTURETYPE_UNSIGNED_SHORT), and updating the function to retrieve the internal sized format in order to be able to return new values as gl.RGBA16UI. Does it seem ok for you ? Moreover, we're still using Engine.TEXTURETYPE_UNSIGNED_INT to refer to both gl.UNSIGNED_INT (only available for depth textures in WebGL 1) and gl.UNSIGNED_BYTE texture types. I think we need to do a breaking change because gl.UNSIGNED_INT is now a valid texture type for unsigned integer textures in WebGL2 like RGBA32UI textures. Valid combinations of internal format, type and internal size format are listed here in table 3.2. Color-renderable and texture-filterable formats are listed here in table 3.13. This info is also gathered here. And this is a bit less exhaustive in WebGL 2 Specs. [EDIT] With WebGL2, specify the internal sized format will be necessary as some combinations of format and type don't lead to a unique internal sized format. For this purpose, we'll need to add internal sized formats as constants in BABYLON.Engine and we won't lean on _getRGBABufferInternalSizedFormat() function anymore. However, only a few combinations fail to give a unique result: - RGBA format + UNSIGNED_BYTE type - RGBA format + UNSIGNED_INT_2_10_10_10_REV type - RGBA format + FLOAT type - RGB format + UNSIGNED_BYTE type - RGB format + HALF_FLOAT type - RGB format + FLOAT type - RG format + FLOAT type - RED format + FLOAT type So we could just ignore them and return a default value in these cases, for now. [EDIT 2] Current type constants: private static _TEXTURETYPE_UNSIGNED_INT = 0; private static _TEXTURETYPE_FLOAT = 1; private static _TEXTURETYPE_HALF_FLOAT = 2; Suggested new type constants: private static _TEXTURETYPE_BYTE = 0; private static _TEXTURETYPE_UNSIGNED_BYTE = 1; private static _TEXTURETYPE_SHORT = 2; private static _TEXTURETYPE_UNSIGNED_SHORT = 3; private static _TEXTURETYPE_INT = 4; private static _TEXTURETYPE_UNSIGNED_INT = 5; private static _TEXTURETYPE_FLOAT = 6; private static _TEXTURETYPE_HALF_FLOAT = 7; private static _TEXTURETYPE_UNSIGNED_SHORT_4_4_4_4 = 8; private static _TEXTURETYPE_UNSIGNED_SHORT_5_5_5_1 = 9; private static _TEXTURETYPE_UNSIGNED_SHORT_5_6_5 = 10; private static _TEXTURETYPE_UNSIGNED_INT_2_10_10_10_REV = 11; private static _TEXTURETYPE_UNSIGNED_INT_24_8 = 12; private static _TEXTURETYPE_UNSIGNED_INT_10F_11F_11F_REV = 13; private static _TEXTURETYPE_UNSIGNED_INT_5_9_9_9_REV = 14; private static _TEXTURETYPE_FLOAT_32_UNSIGNED_INT_24_8_REV = 15; NOTE 1: As every user should use the public constants and not directly the private numbers the constants are bound to, we should be allowed to modify the order (FLOAT will be defined by 6 instead of 1 for instance). If you do not want to change the order of the three first constants already defined, just say it. NOTE 2: UNSIGNED_INT will not refer to UNSIGNED_BYTE anymore. Breaking change. [EDIT 3] Current format constants: private static _TEXTUREFORMAT_ALPHA = 0; private static _TEXTUREFORMAT_LUMINANCE = 1; private static _TEXTUREFORMAT_LUMINANCE_ALPHA = 2; private static _TEXTUREFORMAT_RGB = 4; private static _TEXTUREFORMAT_RGBA = 5; private static _TEXTUREFORMAT_R = 6; private static _TEXTUREFORMAT_RG = 7; NOTE 1: No 3 ? Did I miss something ? NOTE 2 : I personally guess TEXTUREFORMAT_R is not a good idea for 3 reasons: - It's confusing for people already used to WebGL who know it's gl.RED and not gl.R - It doesn't seem really instructive for beginners who will think R is the good naming - Beginners generally don't play with texture formats and types That's why I suggest to create and use TEXTUREFORMAT_RED in the future. And keep TEXTUREFORMAT_R for retrocompatibility. But once again, it's only a suggestion. Suggested new format constants: private static _TEXTUREFORMAT_ALPHA = 0; private static _TEXTUREFORMAT_LUMINANCE = 1; private static _TEXTUREFORMAT_LUMINANCE_ALPHA = 2; private static _TEXTUREFORMAT_RED = 3; private static _TEXTUREFORMAT_R = 3; private static _TEXTUREFORMAT_RG = 4; private static _TEXTUREFORMAT_RGB = 5; private static _TEXTUREFORMAT_RGBA = 6; private static _TEXTUREFORMAT_RED_INTEGER = 7; private static _TEXTUREFORMAT_R_INTEGER = 7; private static _TEXTUREFORMAT_RG_INTEGER = 8; private static _TEXTUREFORMAT_RGB_INTEGER = 9; private static _TEXTUREFORMAT_RGBA_INTEGER = 10; NOTE 1: Once again, we should be allowed to change the order of the first constants as nobody should use the private numbers directly.

Hello ! As WebGL2 comes with new texture formats, I decided to play a bit with them, and it seems to work well in pure WebGL2: https://playground.babylonjs.com/#RBQYSP (If it prints red, that means the RGB texture did work ?) I saw texture format has been added to createRenderTargetTexture function so I wanted to try it out. But whatever I do, I never achieve to create a RGB Render Target Texture. ? This code works to create a RGBA RenderTarget: https://playground.babylonjs.com/#RBQYSP#5 This code fails to create a RGB RenderTarget: https://playground.babylonjs.com/#RBQYSP#6 Framebuffer is incomplete. I already pulled the last version of BJS and added gl.pixelStorei(gl.UNPACK_ALIGNMENT, 1) everywhere but it doesn't help much. I'm struggling with this, I don't understand where something is different from the pure WebGL2 version. I verified InternalSizedFormat, InternalFormat and TextureType and they're OK. If anybody has an idea... Thanks in advance ? PeapBoy

What is the correct image format to use your own decal texture? I tried a lot of different images in my project but none have worked so far except the babylon one. I guess the image must be png and black on white? Here is a playground with one image test : http://www.babylonjs-playground.com/#1BAPRM#159

When a sponsor buys a non exclusive license to your game, do you send them your game code obfuscated or not? And what time frame do you give a sponsor within which you will fix bugs he finds?

What software do people use to create .aac (.m4a) files? I tried using the FFMpeg library with audacity but neither google chrome on desktop or iOS Safari seem to like the files it has created. I saw something online about using VLC but it looked like a bit of a faff to me, the command is buried deep within a nest of menus. Isn't there a simpler way?
