[BUG-214637] LSL Texture Baking

[sl-service-account]

How would you like the feature to work?

key llBakeTexture(integer width, integer height, list parameters);

Parameters are stackable:
Insert a image

[
    BAKE_TEXTURE_IMAGE,
    key Texture, //Base texture
]

Insert a alpha cutaway image(Similar to alpha masks)

[
    BAKE_TEXTURE_ALPHA,
    key Texture, //Alpha texture
]

Colourise the texture(Similar to: Similar to colouring a prim)

[
    BAKE_TEXTURE_TINT,
    vector Tint, //Tint(<1,1,1> for no tinting, <0,0,0> to make it fully black, <1,0,0> to make it tinted red)
]

Shift the hue of the texture(Similar to: Rainbow Colour in Skin editor)

[
    BAKE_TEXTURE_HUE,
    float Hue //0 for 0 hue shift. Question: Should max be 1, 360, or PI?
]

Stacking example:

[
    BAKE_TEXTURE_IMAGE, solid_white_texture, //Solid white background base
    BAKE_TEXTURE_TINT, <255,0,0>, //Colour the background red
    BAKE_TEXTURE_IMAGE, striped_black_texture //Overlay black stripes on it
]

This would result in a red and black striped texture.

Baked textures would be considered temporary assets and deleted when the script's context is destroyed, such as:

• Prim is deleted or taken(NOT take copy)

• Attachment is detached

• Wearing avatar logs off

  To avoid giving pains to the texture baking service, the asset should not be destroyed when:

• Avatar teleports or crosses sim

• Object changes sim

  There should be a limit on how many bakes can be done per minute and per hour(EG: No more than 10 per minute and no more than 50 per hour, personally this seems more than a reasonable amount to me. This being per script) to prevent destruction of the asset server and texture baking service.

  Additionally, this will cause the script to sleep for somewhere between 1 to 5 seconds.

  Why is this feature important to you? How would it benefit the community?

  Honestly, I could have sworn this was suggested before, but I couldn't find it. I searched and searched but it was no where to be found.

  This would be useful to:

• People who use mesh bodies and reduce polygon count as there would be no need for 8 layers of a mesh body stacked upon it's self to do "Tattoo layers" or "Clothing" layers.

• The upcoming Animesh as it would provide the ability to create dynamic NPCs.

• Furry and similar avatars as it would allow baking of marking and other layers while also colouring such layers with tint shifting

Hiya Chaser,

LL have actually started work on the "Bakes on mesh" project.

Hi Chaser,

Great suggestion. We already have a project underway!

Thanks!
