charliejh Posted September 19, 2016 Share Posted September 19, 2016 Hi, Im trying to change the scale of my Alembic camera in Houdini. I have tried using the null node at object level, but it causes issues when I try to render some ocean. I see that you should be able to change the uniform scale deep inside the alembic file in xform. The Uniform Scale is stuck on 1, I cannot edit it (the 1 is inside a yellowish box) which seems to be why I cant change it. Any help appreciated, cheers Charlie Quote Link to comment Share on other sites More sharing options...
celd Posted September 19, 2016 Share Posted September 19, 2016 (edited) you can scale your imported camera by plugging it into a null and scaling the null, you then duplicate the camera, drop fetch and blend nodes and connect it like this: duplicated camera->blend->fetch uncheck SX SY SZ on the blend node, check "use parent transform of fetched object" and zero out all transforms on duplicated camera this way you get translations and rotations of your scaled camera only and wont have render issues due to scaling Edited September 19, 2016 by celd 1 Quote Link to comment Share on other sites More sharing options...
charliejh Posted September 20, 2016 Author Share Posted September 20, 2016 Hi Thanks for the reply, I've managed to do everything except "zeroing out all transforms". How do I do this? Also, when you say duplicate, do you mean copy? as in select - ctrl c -ctrl v the camera? Does the new camera stay connected to my original null node? Thanks Quote Link to comment Share on other sites More sharing options...
celd Posted September 20, 2016 Share Posted September 20, 2016 by zeroing out I mean literally setting its translate and rotation values to zero, also you connected the fetch/blend/camera the other way arround the idea is that fetch node gets the transform values from your imported camera and blend node filters out its scale, then you parent your copied camera which only follows along, reason why you copy it is simply so it has all the camera settings as your imported one also you dont want your fetch to be connected into the null you scale your imported camera with Quote Link to comment Share on other sites More sharing options...
