Simple Photoshop Texture work for a ready UV and 3D model

Hello I have a model in 3 different versions. In level-1 its parts been attached and so model have 9 parts level-2 is around 15 parts level 3 more. Textures and UVs are done too. One last step that I want, is to be able to see and distinguish each model comparing to its next model. And I want to do this by change the brightness of texture of that part. So basically all you need to do is use photoshop and make some parts brighter in the texture. Examples attached. I will provide the model and textures (4 textures) You should copy these 4 textures into all 3 folders of model-versions because their way of attached-together is different so you need to select different parts for each level, and use brightness tool. A simple job for 3D artist, would take less than 2 hours. In attached files I showed you an example of some parts numbered 1,2,3,4 , so thet are brighter and original by after the other, in a zigzag way. or another sample of part 1 and 2 if you see. example : 1 is original texture, 2 is brighter , if there is more parts, then same way, [login to view URL] one by next to it is brighter, thats all the job you need to do. I also need you to rename the parts names. If you do not have samples, or portfolio please do not bid. More projects available for the right freelancer. Budget $20 Thanks.
