I have a problem I cannot resolve, I need some advises.
Please, have a look at the attached images, one has been rendered with OSA and the second one without OSA. The coins are made with a curve circle and the image of 1 EURO is used as texture. The result of the coin images rendered without OSA is great for me but as soon as I activate the OSA to get a more precise result, the coin images become too blured and I lose the nice reflection effect I got without OSA.
Try aktivation two same textures and giving the one only col and the other only nor, that looks crispier than just telling one texture to have both… and you can also lower the filter of the texture a bit to 0.75 or so…
Ok, for the coins I finally made a hires photo of a one Euro coin and it seems to be better.
I have another problem now, I don’t like the non realistic feeling of the result and I think it is mainly due to the poor shadows. But I cannot get a better shadow result, I rendered the scene using Yafray. I would like much more apparent shadows, what parameter in Yafray or elsewhere could I use to get stronger shadows without increasing light ?
