Hi there, I am new to houdini. I was trying to select the objects with the same material and then to assign a new material to them，but I couldn’t find a way. I am a maya user and may not get the logic of Houdini. Could anyone help me out? Thanks

Go to material palette tab, find your material in one of the sub tabs there, select it then click the select button on the top most area of that window and it should select all objects with that material assigned.

Or just run this guys script here https://aboeinghoff.com/select-objects-with-this-material/ [aboeinghoff.com] It will create the option to just right click a material in tree view and click select objects with this material similar to maya.
