Model Specs

[specs for crysis]


ANSWER Weapons (1st person and 3rd person bind models) 1st person: about 6000 triangles (same as cryengine1; not more really needed ? above, normal maps are not needed) 3rd person: about 1500 triangles

Characters As we are using attachments we have to split the triangle numbers in the separate parts: * Heads 3k triangles * Body 5k triangles * Attachments 1 k triangles

Vehicles Max. 20000 polygons is our internal limit

Buildings Hard to answer ? put detail were detail is needed. No real need to go crazy. If you only have a few buildings in your level you can spend more triangles, but you should be careful in City maps.

Vegetation Between 500 and 2500 triangles for trees ?whereas the ones with 2500 should not be used in a dense forest because of the filtrate ? It heavily depends on the scenery you want to create.

Misc entities Depends on the size and the complexity.

If you use one material, 300 polygons for a box are ok. This is the minimum number, one set of material should use in an object, as the setup for the renderer is much heavier compared to the actual rendering of these polygons. This also means you do no need LODs for objects lower then 500-600 triangles (given they only use one material).


How many LODs will be supported in CE2, are you sticking to just the 3 again?


We stick to the 3 LOD's - not a real reason to make 4 (just needs more memory). Polycount is not the big problem when rendering our datasets. Material changes and the resulting draw-calls affect performance much more heavily on modern graphics cards than pure triangle count alone.


What are the texture resolutions for weapons, character, etc. in Crysis?


Weapons 1024×1024; Character head: 512 x 512 to 1024 x 1024; Character body: 1024 x 1024; Attachments: 1024 x 1024.

A general rule should be that you do not extend 170 to 190MB for the targeted Spec including mesh geometry. The last 60 MB (256 ? 60 = 196MB) will be used for dynamic textures (shadow maps). You should therefore divide the available amount by the assets you want to show in the level.

A good advice is to keep the numbers of different materials per object very low and put more polygons into the object. The graphic card can a) handle polygons much better than loading different textures and b) can give you much more detail with lower memory consumption.


The number of materials per building:


From 7 till 20 materials.
