I wish to automate a process of combining Table component renders to create finished table base x table top combinations. A table base can have upto 15 combinations of table tops (varying in colours and materials). There are also metal rims that are an option for each table top......Then there are several bases that this all will be the case for. The amount of tops will vary from base to base.
Each render has a white background and there are alpha makes for each render. So as each render is brought into the photoshop file it needs to masked with the alpha mask. this will enable the bases to be seen through the tops and rims layers.
The image needs to be trimmed of the transparent pixels so image becomes the size of the table combination.
Then Saved out as a jpeg.
Simple Structure of combinations would be something as follows
