Hello Paul Ambrosiussen.
I just noticed this thread - and I am kinda confused to see its empty.
Not sure what it means.
I can say, I am very much interested in LOD creation toolset. I started using Houdini for this task like half a year ago, and, though I love a lot of what I can achieve there is also a lot that could work better for me, thats for sure.
Is there still an interest from your side to work on this?
Thank you
Pavel

Technical Discussion » UV Autoseam merge threshold having no effect?

Hi,
did anyone manage to make UV Autoseam work including the merge threshold to merge islands together? Maybe I do something wrong but I get some spliting based on Distortion tolerance but Merge threshold does not do anything at all …
Thank you for response.

Thank you - I guess this is way past my current abilities, but I will try to dive into it and understand what you wrote here.
To Luiz Kruel - something went a lot wrong after I installed the latest version. Not too sure about what it is, but I have now two simple bakers, one is Gamedev toolkit and one in digital assets … and the one in gamedev toolkit does not bake correctly now (working on other project that does not use cages today and yesterday.. so not sure yet how about cage use) .. the one in digital assets works as it used to do.
I guess it should work as it used to do without a cage, with fixed behavior when cage is used … so not really sure whats happening with it now.

Thank you for clarification. I understand that part and its just half of the baking artifacts I am trying to get rid of, the other half is connected with variable Ray Bias needs of the mesh - could you please point me to a way how do you manipulate the ray bias per point please? I tried to create an attribute, but totally failed trying to feed it into Ray Bias field.

Oh … and two more questions
Should I be able to get groups, parts, selection sets when importing fbx? So far I am able to get in only materials, but not other attributes (though they are exported and when I check the file they are there - exporting to fbx from Modo) ..
And - cage and Ray Bias … how the Ray Bias works when cage is used? Does it multiply the cage offset or overwrite it?
Thank you once again

Hello Luiz,
great - thank you very much, it will help me a lot if I could use cage to correct the baking errors.
May I ask few questions so that I know I understand it all well? (Ray bias I did use but I have so much variation in the highpoly that I would need to have it defined per point in attribute, which I tried but was not able to make it work)
The cage should change the direction from the lowpoly mesh normal … so I can do a full smooth and offset to make a cage and get rid of discontinuity problems - right? That is a description in docs …
Does the cage also work to change the distance (Ray Bias ? ) according to how much I offset the points? That how a cage was used in other SW for baking so I hope I can use it too to correct some problematic areas that need high/low bias …
What is a correct way to get better quality AO? For now what I do is I unlock the asset foch editing, dive like three levels deep and change sampling from 2 2 to like 8 8 and get much smoother ao with way less noise. But I still think I am not seeing the propper way to do it that would not need edits inside the HDA and would use parameters exposed? I tried but did not get anything less noisy …
Thank you
Pavel

So I just thought - as baking is this regular part of game asset creation - that someone with more experience with using houdini game baking tools will be able to point me in the right direction. I really know very little about Mantra and rendering pipeline in Houdini … I am used to do so in different packages so I have lots of experience there but Houdini is so much different that cant analyze using some deeper knowledge there.

I can not share the hip - as I am under NDA. If I am too hopeless I will try to make some sample that does not show anything important and post it, but simply put I have higpoly and lowpoly … use simple baker … lowpoly had UVs made … and softened normals with the tool from gamedev toolset. I tune all I need this way and baking works well .. with some issues that I want to solve by cage. So - I peak outwards the lowpoly with fully softened normals to make a cage .. and “throw” the peak node into cage field of simple baker. Then it breaks

But if what you say is true - that you tried *everything* - then this cannot be the problem, obviously. If you really tried *everything*, I am lost and apologize.
Ok .. well … I have just been really frustrated and my everything ment fiddling with exposed parameters of simple baker and also diving into the asset and trying to find some solution there, and also saving the cage and highres mesh to disk and loading from there. Also I did try to use just some testmesh (pighead) and - I did bake something (as oposed to nothing) using that but with lots of baking errors that should not be there. so .. not EVERYTHING … more like everything I was able to think about and try, right?
I understand what you mean - but I just used peak on the lowpoly mesh to make cage .. all the normals of the polys are facing the same way as the were on lowpoly. I may try reversing them (which I did not do yet) though it sounds weird - the cage should (from description in docs) be used to make a new direction to be used for projection instead of regular normal … and that new direction is made from coresponding points on cage and lowpoly … and those should be moved outwards (from docs description).
Also … because with the pighead it kinda worked … without reverting … I guess I should not be the case. Kinda worked but never really worked .. always had defects and errors in the render that were not present in bake without a cage.
The documentation does not say too much about it … and (probably because I am very new to houdini) I feel like its ment to be really easy to use yet it never works for me so I think I just dont understand some part correctly and use it in a wrong way.

Please if anybody knows how to make it work, I am really stuck without a clue now, but I need it working really fast for the final quality bakes.

Hello,
I am trying to use Simple baker for one project - preparing a lot of parts for realtime - and all is fine and well up to a point where I want/need to use Cage to get rid of some artifacts (and hopefully also controll distance for baking locally - cage is usually used for this too).
But when I do input a cage all I get is a blank render, and nothing at all that I tried seems to change it … Could someone please help me to get a working bake with cage?
(My approach was to tune it all how I need without using cage … then I just peak my lowpoly after smoothing its normal and feed the peak node into cage field… I also tried saving it to disk .. puting it into a different OBJ … changing parameters that might affect it … but really all I get is nothing when I plug in a cage … up to that point all works well and bakes well)
Thank you

Technical Discussion » Working with imported FBX hierarchy - bunch of questions

Hello,
I am trying to do some cleanup adn reduction to data I recieved in FBX format (its 40+ million poly, 20k items … quite a complex data)
I would like to know if there is (after import of the hierarchical data with thousands of nulls and items and correcting some errors that are there on some parts) a possibility to merge it into a blank geometry node without the need to add one sop at a time .. or doing a physical merge of all the data into one node …. can I say .. .please look on anything that is parented to this null and merge me any geometry here?
Another question that has to do with this data is - if I have many separate islands of polygons, separated by narrow bands of missing polygons … is there any automatic way to fill in those strips of polygons? I tried a few but all need some intervention and the amount of data to be manualy selected is quite high … so being able to to do it without any selection or group making would be the best way if there one … I will then merge and reduce it to a very lowpoly state … but need to create the continuous shell to be able to reduce it well.
Thank you
Pavel
