@Dr-Sassi i'm a lot comfier in Flame - its where i spend all my working time, and only occasionally get the chance to stretch out into C4d - which is why your help is so invaluable every few months!

Sometimes i do my 3d inside Flame - Renderdome Bandit - this was a competition entry i created wholly within Flame (and it came 3rd), but it is not easy to create complex 3d so i prefer to use Cinema for that.

I have tried reading through the Aces Central a few times in the past but it rapidly gets very confusing and just leaves me bewildered.

best wishes
Adam

nice explanation...thanks.
I tried some render tests which i then brought in Flame to check. I had come to the same conclusion that with OpenEXR as the export type, and setting the aces output to raw in the redshift render settings gives me the most flexibility in post.

I'm very new to using Redshift and i'm puzzled by a issue i am seeing during the render process, that i don't know how to begin solving.

When rendering, in the C4d Picture Viewer, i can watch the progress and the colour on the render looks great - exactly as i wanted, but the instant the render for that frame ends, the image changes and the colours all become darker and more saturated

can anyone suggest where the issue might be originating? I am working my way through greyscale gorrila redshift tutorial - but its 16 hours long and very in depth, and way above my level of knowledge!

@Dr-Sassi
THANK YOU!!

I tried the different settings as suggested and found that using Box as the size caused other problems ( the bricks piled too high in the box to close it!). I had been using Automatic before and it was still piling too high, but not as high as with Box.

So tried a couple of other Shapes and found Ellipsoid works perfectly (with shape size set to 0mm)...a good drop of bricks with much less explosion, and it also lays much more level making the animation work as intended.

best regards

@Dr-Sassi thank you for the explanation...makes a lot of sense when you explain it like that.

I do have one question...
i reset the dynamics on my model to match yours and i noticed that the very start of the animation when the bricks start to fall, they seem to explode outwards in all directions, and when the gravity is lower this explosion appears larger (obviously lower gravity lets the particles move further before they are caught and pulled down).

What causes this explosion to happen? in the absence of any other applied force i would expect things to simply fall downwards not outwards.

i think i might have solved the problems (almost !)
By changing the shape and size of the funnel - i am no longer loosing bricks outside the drop zone.
The Project Settings/Bullet need these settings - Collision Margin - 0.5mm, Scale 6.5mm, Steps per frame -30, Solver Iterations - 30
Now the bricks are behaving almost exactly as i want - the wireframe show a few breaking through the base of the tray, but as they are not seen i'm less concerned.

@Dr-Sassi - thanks...just uploaded the files. You might recognise the project as the same one you have already given me invaluable help with!!

i have got a bit further...
i found a different set of Project Settings called Bullet - and i here found a Collision Margin setting set to 1cm. I dropped it to 2mm and the floating seems to be resolved, but now the bricks are definitely breaking through the model . I also set the Scene Scale back to 1000mm and its made no difference.

How do stop the breaking through from happening?

I have modelled a tray into which i have a thousand small coloured bricks being dropped in.

The bricks are being directed into the tray using an invisible funnel - because my cloner object is using an image object to control the colours of the clones and is too wide to drop in cleanly.

I have a Collider body tag on both the tray and the funnel, and i have a rigid dynamics tag on the cloner object.

When i run the simulation the bricks fall in, but then they float above the tray base and they stay roughly a centimetre from the tray walls. It also appears that the floating plane is not perfectly flat but tilting to one side and some of the bricks are breaking through the tray base slightly.

please can you suggest areas that might be the issue?
i cannot see any settings that would suggest a "force field" around the boundaries. I have also set the Scene Scale (in Project settings/Simulation to 6.5mm because that is the size of each brick, and i was told to match those to help stop the bricks vibrating constantly.

i tried to add a project file but i cannot make it smaller than 3.2mb and the upload says theres a limit of 2mb files.

thanks

I have been trying to get the Fold My Design preset to work but i keep coming up with problems and i cannot find any info that might help explain fixes.

I have a box design that i want to replicate, and have tried using splines created and exported with Illustrator (v8) and i have also recreated the splines within C4d. One of the shapes (a rectangle with a shaped top edge to mirror the design) always shows up as Red and refuses to be part of the setup.

I have no idea how to make this shape acceptable. I have tried changing the spline type, changing the intermediate points , moving the start end points. Nothing seems to work.

The second issue is that almost all the panels are being split into oddly divided triangular facets. None of the tutorials i have watched seem to mention ways to address these issues.

Can anyone point me towards a solution for these?
thanks
