Is there an easy way to change the material name or color of an object?

Hello,
I would like to change the color of a sphere (live).
I have tried few things with the 'graphic' property, but without success.
auto & list = raisim::OgreVis::get()->getVisualObjectList();
list['sphere'].graphics->...
I would need help on that one.
Thanks!
This is definitely tricky. I will try to make a simpler way. But the current way is
auto *ogreEntity = dynamic_cast<Ogre::Entity *>(list["sphere"].graphics->getAttachedObject(0));
ogreEntity->getSubEntities()[0]->setMaterialName("red");Hi Jemin,
I have tried your solution (and some variations) and I keep getting segmentation faults.
This is not critical to me though. I found an (not ideal) alternative to present the info I want.
Thanks!
It's hard to see how a segmentation fault can occur here. The only way that I can think of is when "sphere" doesn't exist. Do you use debug_app? For me, it is impossible to develop an environment with the debug_app. Clion has a built-in support for valgrind and it is a HIGHLY HIGHLY recommended way. Make sure that you get no errors with "no_render" first, then use rendering. Valgrind outputs many errors with opengl functions but these are safe ones. You can also try GDB first.
By the way, the code snippet I wrote is what I use in my environment. I just copy-pasted it here
