Shaders and their effect on render time question

drucdruc Posts: 472
in Technical Help (nuts n bolts)

I have been using shaders to convert Billy-T's Custom bikes, Type 1, 2 and 3. When I had one in the scene with Franklin Square as the back ground, 3 G8 characters in their biker clothing (redone Desperado for G8M and both biker outfits from Bad Kitten Co for G8F) the render time was quite quick.

When I changed the scene to place G8 characters and bike on Road to nowhere. I added a second bike, also shaders used to convert to Iray and added Retro Pick up, using both the Environment map in the sky that comes with Road to Nowhere or USXT with a very light on biome, the render is taking more than one day.

Is this the result of the large use of shaders or have I simply over loaded the scene?

Best regards and thanks for looking.

    That sounds as if the extra content has tipped the scene over the limt that the GPU can handle and it is now using only the CPU, which is much slower. Check the log file (Help>Troubleshooting>View Log File) and iif it is a memory issue try restarting DS and then render immediately. If it is memory and a restart doesn't help you will need to work out how much too big it is (the log should help) and optimise - e.g. use reduced size textuers on clothes and figues if they are smaller than their textures in the final render (or get rid of maps that won't be seen entirely, I magine the legs are probably laergely or wholly hidden for example).

    Thanks Richard, you could very well be correct. I used the 4k versions of the shaders for example and there are lots of them so adding a second bike basically doubled up of the memory requirements.

    DS/Iray should be able to avoid loading multiple co[ies of the same maps.
