  1. @Everyone, thanks for your help! @JakeL, Lumen 2 looks interesting, thanks for the heads up! As I'm no expert in cinema 4d, I haven't gotten the multipassing to work the way I want, when using GI. With standard lights, I have, but not with GI. Do you have any links that could help me with this (especially rendering the shadow as a separate layer)?
  2. That's a very good site for hdr imaging, thank you. Does anyone have any good sites/tutorials especially for blending cg with photos? I still haven't quite figured out how to export my rendered object in to photoshop, with the shadows, but no floor. Is this even possible with global illumination? If not, what is the best approach for doing this?
  3. I definitively want to learn more about HDR lighting, but I am quite convinced its possible to achieve good result without having to use extra lights. Of course I can add the extra lights, but I still want to have as good starting point as possible. Should I rather start learning other 3d tools with better photorealism renderers than c4d (3dsmax?)? Maybe vray for c4d is a good starting point? My goal is to be able to blend CG in photos as seamlessly as possible, so where should I go from here? Any tips?
  4. Thank you, that's a bit helpfull. It's definitively getting closer, but I'm still not there yet. I'm pretty sure the shadow would be sharper from the ceiling light. This is my closest result using your numbers: Is this the same as you got? Any hdri experts out there? Also, does anyone know how to export the sphere to photoshop without the floor, but keeping the shadows? I cant seem to find a good way, using hdri lighting. With normal lights I know it's possible.
  5. Hmm, that sounds a bit strange, who would put lights in a tutorial where the hdri lighting is the whole point? If you look at this hdri tutorial, you can see the same type of shadows being cast. Here: Sure I could add some lights to get the shadows, but its not very easy recreating the kind of shadows you see on the image to the right. With my intentions on compositing my 3d objects in photos with "real" shadows, it would help a lot if the hdri lighting would act like in the tutorials.
  6. Thank you for your answer! I have actually tried the new method with the sky + hdr material and playing with the exposure, hdr gamma, black point, white point, -still the same soft shadow.. Is anybody able to get the same result as in the tutorial? (Two main shadows, cold and warm light.) You can get the hdri angular map here: http://www.debevec.org/Probes/kitchen_probe.hdr cheers!
  7. Hello! I am an advertising photographer that is quite new to 3d, but is planning to get good enough to be able to incorporate 3d in my photography. My understanding is that hdri and global illumination is the way to go to match the lighting and reflections in a real world scene. I am trying to follow this tutorial, but I don't get the same shadows and light color as in the tutorial. I'm using Cinema 4d R11.5, but I had the same problem with R10 and R11 also. --------------------------------This is the result in the tutorial ----------------------------------------------------------------------------This is my result---------------------------------------------- What am I doing wrong? What render settings should I use? When I used R10 with the old GI-engine (like in the tutorial) I had the correct settings, but still got the same result. I seem to get a soft shadow no matter what I do. I have also tried with my own made hdri maps, but still to soft shadows (hard shadows in real life). Also I am wondering how to export my rendered object(s) with shadows (without the floor object), from cinema 4d to photoshop, using global illumination as lighting. My goal is to put them seamlessly into photos. (Sorry my english, I am from Norway;)
