Layout Scale
- Make sure the UV Islands have the correct scale. The main square in the UV Editor is considered to be 1m x 1m. So the layout on the whole model needs to be scaled proportionally according to the size of the actual model in the scene.
- Since the main square is considered to be 1 meter, that means that each little square will be 5 cm because there are 20 small squares in the main square.
- With the grid set to the correct dimensions (see Grid Dimensions) and using the Cylindo UVWScale checker from the modeling panel,you can easily scale the layout by making the squares from the texture match the squares from the grid.
Layout Orientation
- Make sure that the orientation/rotation of each of the UV islands is in the correct direction. The layout shells should always be rotated so that the direction is always facing forward toward the point of view.

Correct Layout Orientation |
- For wood parts (e.g. table tops, wooden legs, cabinets, etc.), the UV Islands must always be placed horizontally in the UV editor. It doesn’t matter which way they are facing as long as they are placed horizontally and the layout flows along the longest side of the surface.
Layout Placement
- The UV Islands inside the UV Editor must be placed in the main square between 0,0 and 1,1 coordinates as well as with the correct placement in regards to each other. The reason for this is to make sure that if there are patterned materials that there will be a flow of the pattern through all of the elements of the product.
- Here is an extensive video guide for the placement of the UV Layout
- For wood, metal, glass, and other such materials, there are no placement rules in regards to the layout. The only rule is that the UV Shells are all rotated horizontally.
- The only exception is the plywood parts, where the layout needs to be rotated horizontally and be placed by absolute world transform on U: 0.5 x V: 0.5 in the UV Editor coordinates.
