Modelling the Avatar
This doc goes over creating your custom avatar for Roblox and considerations to keep in mind when doing so.
With your reference board or character design clear in your head we can start building the character.
The two main things to keep in mind is that your character needs to be humanoid (if creating a standard avatar).
There are standard character sizes that Roblox uses and some examples of these are included in the file as guides as Classic, Normal, and Slender. Any reference assets you use should not be exported with the character.
Hide all the assets in the template for now.
Creating the Character
Create the Character model. There are many resources online for this process.
The Avatar Introduction doc looked at Capping body parts in order to align with the standard Roblox Avatar approach. In order to simplify and speed up the rigging process it is better to do this after the skinning process.
Make sure that the triangle count falls under the following by going to the Overlay options and selecting Statistics :
Head - 4000
Upper & Lower Torso - 1750
Right Arm (UpperArm, LowerArm & Hand) - 1248
Left Arm (UpperArm, LowerArm & Hand) - 1248
Right Leg (UpperLeg, LowerLeg, & Foot) - 1248
Left Leg (UpperLeg, LowerLeg, & Foot) - 1248
Total - 10,742
Your Avatar should be set to an I pose. Do not use an A Pose or T Pose. This could be done setting the pose after rigging according to the Roblox Docs.
Final Check
Have all the same meshes as the template with the correct naming conventions
Head_Geo
UpperTorso_Geo
LeftUpperArm_Geo
RightUpperArm_Geo
LeftLowerArm_Geo
RightLowerArm_Geo
LeftHand_Geo
RightHand_Geo
LowerTorso_Geo
LeftUpperLeg_Geo
RightUpperLeg_Geo
LeftLowerLeg_Geo
RightLowerLeg_Geo
LeftFoot_Geo
RightFoot_Geo
The Character is in an I Pose.
The Character is facing the right direction and has the right scale.
The Meshes all have Applied Transforms (Ctrl + A in Blender) so that :
Scale is 1.0.
Position is 0,0,0.
Rotation is 0,0,0.
Polycount is below the maximum :
Head - 4000
Upper & Lower Torso - 1750
Right Arm (UpperArm, LowerArm & Hand) - 1248
Left Arm (UpperArm, LowerArm & Hand) - 1248
Right Leg (UpperLeg, LowerLeg, & Foot) - 1248
Left Leg (UpperLeg, LowerLeg, & Foot) - 1248
Total - 10,742
