Hi guys, 
I am doing a research about 3D modular design.
 so please, can you help me to answer these questions.

any help guys its important for my subject 
theres around 10 question all related to 3d modular.
please help me

you can answer it here : 

1- What is the better way to match the modular pieces element model with independent pieces elements of the environment?

 2- Nowadays there is snap tool that allow snapping using vertex in game engines. Do you still prefer using grid system? Please state the reason.

 3-  What is the specific way to add the decals on 3D object and how to create a convincing decals?

 4- What is the best way to add lights to break the repetition modular? Please state the reason.

 5- Is there any other way to break the repetition in 3d modular except adding lights and which is the best way? Please state the reason.

 6- How to decide the measurement in determining the size of the repeated unit and the size of texture and UV?

 7- Any technique or advice related to 3d modular that noteworthy? If yes, please state it below.

 8- Is it better to add different texture while changing colors texture from materials in the game engine?

Example: red color brick wall, add hue and saturation in material to change the brick wall to blue.

 9- How to deal with LOD in 3d modular for example buildings, do you set all buildings in one LOD or some parts? Please state the reason.

 10- What is the best workflow for making 3D modular? Please answer it in point form.

thanks
