True, using our textures can be very demanding for both, software and hardware. Here some general advice:
- Upgrade RAM: Simple enough, this often is the most effective solution. We recommend a minimum of 4GB (along with a 64bit OS). Better make it 8 or more. RAM is too cheap to let the lack of it slow you down!
- Downgrade textures: In many cases your scene doesn't require all of the textures to be loaded in their full resolution. We recommend to create different versions of every map with 1/2, 1/4rd and 1/8th of the original resolution and use them according to the requirements of your scene. BTW, JPEGing the maps only saves disk space. Decompressed, a JPEG image occupies the same amount of memory as a PNG image.
- Downgrade settings: Many render applications employ sophisticated techniques to maximize rendering quality, e.g. advanced texture filtering. Some of those can use up a great amount of memory. For example, in 3dsmax the filter mode 'Summed area', while significantly enhancing quality, takes about four times as much memory as the default setting 'Pyramidal'.
- Render in parts: If none of the above is enough, you might want to consider rendering your scene in several parts or layers, each containing only the amount of textures your system can handle.
