Tutorial - creating a low-poly badge (Carrara and Hexagon)
How to create a low-poly badge.
This will be a two part tutorial
It also covers only the basics, so you need a working knowledge in how to use Carrara and Hexagon.
To create a texture-map and bump-map with Carrara.
You have created your model in Hexagon. This one is 36 000 poly's. Way to high for Poser or DAZ Studio. So you want to make a low-poly version.
Export the model to a .obj file. Export-scale doesn't matter. 1 is fine. This model is just for creating texture-maps.
Import the model into Carrara. Posision it in the assembly-room.
If you are using metalic shaders, it is also important to give them something to reflect in the background. The choise of background will also affect the resulting reflected color of the shader.
Setup the lights.
Select the camera in the assembly room.
1. Change it to Isometric
2. Posision the camera. If you turn on "ShowProductionFrame" in the vieW meny it is much easier. Also remember to set the image size (in the render room) to something like 1024x1024 (or bigger)
3. Use the Zoom to fill out the productionframe. The scroll wheel wouldn't work when using a Isometric Camera.
In the rendering tab- make it as high quality as posible, but you shouldn't need any Global Ilumination.
In the Output tab - Your image size should already been set to something square(see camera setup).
Under Multi-Pass press add- then in the pop-up window- select depth.
This will give you a greyscale image of the depht of your image.
To use this as a bump- or displacment-map, you have to take it into a photoeditor and invert the colors, so that what's black will be white and the higest points and what's white will be black and the lowest point.
