Support / Removing the orthographic lock on tk2d camera?

« on: May 03, 2013, 04:26:30 am »

Hello,

Just a quick question:
Is it safe to remove the orthographic lock from the tk2d Camera, or would it create a problem with some of the other options? I really enjoy how optimized the camera, and would like to use some of it's functions with my project. I require a perspective camera for the 3D objects that make up the scene, but the player/npcs are all 2D sprites.

Thanks.

Support / 2D Sprite Sizes in a 3D Environment?

« on: April 26, 2013, 07:37:11 pm »

Hello,

I'm currently learning everything I need to know about using Unity as well as 2D Toolkit in order to create a game combining both 2D and 3D. The environments will be 3D while the sprites and background will be 2D.

My question is regarding the physics engine in Unity and how there is a specific size requirement for objects to be able to function properly with Unity's physics.
I understand that in Unity, 1 Unit = 1 Meter, so with that in mind I created a 3D object about 2 meters in height and 1 meter in both length and width as a character size reference. I then created a character sprite with a size of 256 in length and 512 in height. Once imported, I placed both of them into a scene with the scale set to 1 in all axis for both objects and saw that the sprite character was very close to that of the 3D size reference, so I knew I was on the right track. However, I know that if I were to create many sprites at the this size it could end up creating many atlases which could become a possible memory issue in the future.

When combining sprites with 3D environments in unity, is it necessary to stay within Unity's measurement system, or would I be able to get away with creating smaller sized  characters and not create any issues with the physics?
I honestly have no problem creating sprites at the large size mentioned above, and I would actually prefer it, but as mentioned I plan on creating many sprites, and would like to avoid risking any issue with memory or atlas sizes.

Thanks.
