⭐⭐⭐⭐⭐

Have you ever wanted to show your physical ability and/or muscle while wielding the Rexouium avatar? Now, this texture pack is tailor-made especially for you.

These textures work with the Rexouium by Ryzello Riker.

Comes with body texture mappings for two versions: with and without fluff on the chest and back.

The example body textures shown in the product pictures are also included.

This purchase includes:

4K Muscle normal map for the avatar
4K Muscular ambient occlusion map for the avatar
4K Muscle cavity map for additional shadings in software like Substance Painter
4K Muscle shading map and mask for enhancing cavity shadings in 2D editing software (supports layer multiplying, e.g., Photoshop, Krita) or Substance Painter.
4K Muscle thickness map for enhancing the muscle shadings or adding beautiful subsurface scattering effects.
4K Body Texture Set for the white model shown in the picture and Unity Material file for the Poyiomi settings reference.

This purchase does NOT include:

Any default or edited files belonging to the base Rexouium package.
Any files belonging to the Magpie Female edit by Kurai Kitsune.

Please note that there are visible artifacts when the fluff is flattened which is an unfortunate feature of Unity and Rexouium base. To reduce the effect, I have provided instructions in the FAQ to setup your Unity project with an extra package.

DO:

REQUIREMENTS:

Knowledge of how to move textures into your Unity project and apply them to the character model.

Basic use (for the normal and ambient occlusion maps):

Open the files received from this purchase

Drag and drop them into the Materials section of the Rexouium.
Replace the Texture in each of the material spheres with the new corresponding textures.

More advanced (shading, thickness, cavity etc maps):

Ability to use 2D image editing software for texture layering.

and/or

Substance Painter 3D or similar for texture layering.

FAQ:

How to add AO and normal map with Poyiomi?

Open the received files.
Drag and drop the AO and normal map textures into their body material slots.
For realistic and strong shadows, have "Realistic" or "Wrapped" Lighting Type selected under "Shading".
With Toon lighting, to make the normals show, you should enable Rim Lighting and adjust the settings.

You should consider adding shading to the color map for an extra oomph for the muscles.

The normal map is in OpenGL format.

Optional: How to use the shading map?

The shading map changes the tones of the muscle cavities to darker colors and accentuates them.

Adding shading to an existing color texture:

1. In 2D Programs:

Open your Body texture.
Create an additional layer above the texture.
Place the shading on that layer and change the layer type to Multiply.
Duplicate the layer to intensify the effect as needed.
Save as .png or another flat image format for Unity texture use.

2. In Substance Painter:

Create a fill layer at the top of the Body Texture Set.
Import the body shading map texture.
Set the body shading as the base color for the fill layer.
Change layer type to Multiply and duplicate the layer to intensify the effect as needed.

3. In Unity (for Poyiomi shader):

See the instruction image in the pics/ in the delivered .zip file.
Enable Color & Normals > Details
Drag & Drop Shading map into Detail Texture slot.
Set Detail Texture Global Mask to Multiply.
Adjust Detail Texture Tint (white or some light tint), Detail Tex Intensity and Detail Brightness to your liking.

Optional: How to reduce normal map artifacts with flattened fluff?

There are visible normal map artifacts when the fluff is flattened. They are present in the base Rexouium as well, and are not exclusive to this texture set.

The Prefabulous Avatar Unity package by Haï~ (https://docs.hai-vr.dev/docs/products/prefabulous-avatar) allows normal recalculation in Unity without altering the avatar itself, and is able to reduce the artifacts.

The working principle is technical, but the installation and usage is fairly straightforward with some Unity knowledge.

After the installation of Prefabulous Avatar in Unity:

See the instructions at https://docs.hai-vr.dev/docs/products/prefabulous-avatar/hai-components/recalculate-normals.
Add a "PA-H Recalculate Normals" component anywhere in your avatar.
Add blend shapes that you want to recalculate, mainly "Floof_Back_Flat", "Floof_BckHips_Flat" and "Floof_Shoulders_Flat". Consider adding any blendshapes that greatly change the body shape, such as any "Muscle" blend shape.

This is a digital product, so there will be no refunds once purchased.
